Introduction

Association for Computing Machinery is the world’s largest educational and scientific
computing society, which delivers resources that advance computing as a science and a
profession1 . It was one of the early adopters of TEX for its typesetting.
It provided several different classes for a number of journal and conference proceedings. Unfortunately during the years since these classes were written, the code was
patched many times, and the support of the different versions of the classes became
difficult.
This package provides the uniform interface for all ACM publications. It is intended
to replace all different classes and packages and provide an up to date LATEX package.
The package uses only free TEX packages and fonts included in TEXLive, MikTEX
and other popular TEX distributions. It is intended to be published in these distributions
itself, which minimizes users’ efforts in the installation and support of the package.
I am grateful to Michael D. Adams, Leif Andersen, Dirk Beyer, Benjamin Byholm,
Michael Ekstrand, Matthew Fluet, Paolo G. Giarrusso, Ben Greenman, LianTze Lim, Ben
Liblit, Kai Mindermann, Frank Mittelbach, Ross Moore, John Owens, Joel Nider, Tobias Pape, Mathias Rav, Matteo Riondato, Craig Rodkin, Bernard Rous, David Shamma,
Stephen Spencer, John Wickerson, and many others for their invaluable help.
The development version of the package is available at https://github.com/
borisveytsman/acmart.

User’s guide

The class uses many commands and customizaton options, so it might appear intimidating for a casual user. Do not panic! Many of these commands and options can
be safely left with their default values, or the values recommended by your conference or journal editors. If you have problems or questions, do not hesitate to ask me
directly or the community at https://github.com/borisveytsman/acmart, https:
//tex.stackexchange.com or the closest TEX Users Group. The world-wide TEX Users
Group is at https://tug.org/; please consider joining us if you use TEX regularly.

2.1

Installation

Most probably, you already have this package installed in your favorite TEX distribution;
if not, you may want to upgrade. You may need to upgrade it anyway since the package
uses a number of relatively recent packages, especially the ones related to the fonts.
The latest released version of the package can be found on CTAN: https://www.
ctan.org/pkg/acmart. The development version can be found on GitHub: https://
github.com/borisveytsman/acmart. At this address you can file a bug report—or even
contribute your own enhancement making a pull request.
Most users should not attempt to install this package themselves, and rather rely on
their TEX distributions to provide it. If you decide to install the package yourself, follow
the standard rules:
1 http://www.acm.org/

3

1. Run latex on acmart.ins. This will produce the file acmart.cls
2. Put the file acmart.cls and the bibliography files *.bst to the places where LATEX
can find them (see [1] or the documentation for your TEX system).
3. Update the database of file names. Again, see [1] or the documentation for your
TEX system for the system-specific details.
4. The file acmart.pdf provides the documentation for the package (this is the file
you are probably reading now).
As an alternative to items 2 and 3 you can just put the files in the working directory
where your .tex file is.
The class uses a number of other packages. They are included in all major TEX distributions (TEXLive, MacTEX, MikTEX) of 2015 and later, so you probably have them
installed. Just in case here is the list of these packages:

2.2

Invocation and options

To use the class put in the preamble of your document
\documentclass[hoptionsi]{acmart}
There are several options corresponding to the type of the document and its general
appearance. They are described below. Generally speaking, the options have key=value
forms, for example
\documentclass[format=acmsmall, screen=true, review=false]{acmart}

5

Table 1: The possible values for the format option

manuscript
acmsmall

A manuscript. This is the default
Small single column format, used for CIE, CSUR, JACM, JDIQ, JEA,
JERIC, JETC, PACMHCI, PACMPL, TAAS, TACCESS, TACO, TALG,
TALLIP (formerly TALIP), TCPS, TEAC, TECS, THRI, TIIS, TISSEC,
TIST, TKDD, TMIS, TOCE, TOCHI, TOCL, TOCS, TOCT, TODAES,
TODS, TOIS, TOIT, TOMACS, TOMM (formerly TOMCCAP), TOMPECS, TOMS, TOPC, TOPLAS, TOPS, TOS, TOSEM, TOSN, TRETS,
TSAS, TSC, TSLP, TWEB, including special issues.
Large single column format, used for IMWUT, JOCCH, POMACS,
TAP, including special issues.
Large double column format, used for TOG, including special issues.
Proceedings format for most of ACM conferences (with the exceptions
listed below) and all ICPS volumes.
As of March 2017, this format is no longer used. Please use sigconf
for SIGGRAPH conferences.
Proceedings format for SIGPLAN conferences.
Proceedings format for SIGCHI conferences.
Format for SIGCHI extended abstract.

acmlarge
acmtog
sigconf
siggraph
sigplan
sigchi
sigchi-a

The option format describes the format of the output. There are several possible
values for this option, for example,
\documentclass[format=acmtog]{acmart}

Actually the words format= can be omitted, e.g.,
\documentclass[acmtog, review=false]{acmart}

The possible formats are listed in Table 1. Note that formats starting with acm are intended for journals and transactions, while formats starting with sig are intended for
proceedings published as books.
Note that sometimes conference proceedings are published as a special issue (or issues) of an ACM journal. In this case you should use the journal format for a conference
paper. Please contact your conference committee if in doubt.
There are several Boolean options which can take true or false values. They are
listed in Table 2. The words =true can be omitted when setting the Boolean option, so
instead of screen=true one can write just screen, for example,
\documentclass[acmsmall, screen, review]{acmart}

The option review is useful when combined with the manuscript format option: it
provides a version suitable for reviewers and copyeditors.

A review version: lines are numbered, hyperlinks are
colored
A screen version: hyperlinks are colored
Whether to use natbib package (see Section 2.10)
Whether to make author(s) anonymous
Whether to generate a special version for authors’ personal use or posting (see Section 2.3)
Whether to put a time stamp in the footer of each page
Whether author’s draft mode is enabled
Whether to define theorem-like environments, see Section 2.6

The default for the option screen depends on the publication. At present it is false
for all publications but PACM, since PACM is now electronic-only. Thus PACM titles
(see Table 3 set this option to true. This option may in the future involve additional
features suitable for on-screen versions of the articles.
The option natbib is used when the corresponding BibTEX style is based on natbib.
In most cases you do not need to set it. See Section 2.10.
The option anonymous is used for anonymous review process: all author information
becomes obscured.
The option timestamp is used to include a time stamp in the footer of each page.
When preparing a document, this can help avoid confusing different revisions. The
footer also include the page range of the document. This helps detect missing pages
in hard copies.
The option authordraft is intended for the authors’ drafts, not intended for distribution. It typesets copyright block to give the authors the idea of its size and overall
size of the paper, but overprints it with the phrase “Unpublished working draft. Not
for distribution”, which also is used as a watermark. This option sets timestamp and
review to true, but these decisions can be overriden by setting these options to false
after authordraft.

2.3

Topmatter commands

A number of commands set up top matter information, or, in the computer science jargon, metadata for the article. They establish the publication name, article title, authors,
doi and other data. Some of these commands, like \title or \author, should be put by
the authors. Others, like \acmVolume or \acmDOI—by the editors. Below we describe
these commands and mention who should issue them. These macros should be used before the \maketitle command. Note that in the previous versions of ACM classes some
of these commands should be used before \maketitle, and some after it. Now they all
must be used before \maketitle.

7

\acmJournal

The class internally loads amsart class, so many top matter commands are inherited
from amsart [2].
The macro \acmJournal{hshortNamei} sets the name of the journal or transaction
for journals and transactions. The argument is the short name of the publication in
uppercase, for example,
\acmJournal{TOMS}

\acmConference

The currently recognized journals are listed in Table 3. Note that conference proceedings
published in book form do not set this macro.
It is expected that this command is inserted by the author of the manuscript when
she decides to which journal to submit the manuscript.
The macro \acmConference[hshort namei]{hnamei}{hdatei}{hvenuei} is used for
conference proceedings published in the book form. The arguments are the following:
short name: the abbreviated name of the conference (optional).
name: the name of the conference.
date: the date(s) of the conference.
venue: the place of the conference.
Examples:
\acmConference[TD’15]{Technical Data Conference}{November
12--16}{Dallas, TX, USA}
\acmConference{SA’15 Art Papers}{November 02--06, 2015}{Kobe, Japan}

\acmBooktitle

By default we assume that the conference proceedings are published in the book
named Proceedings of CONFERENCE, where CONFERENCE is the name of the conference
inferred from the command \acmConference above. However, sometimes the book title
is different. The command \acmBooktitle may be used to set this title, for example,
\acmBooktitle{Companion to the first International Conference on the
Art, Science and Engineering of Programming (Programming ’17)}

\editor

In most cases conference proceedings are edited. You can use the command
\editor[heditori] to set the editor of the volume. This command can be repeated, for
example,
\editor{Jennifer B. Sartor}
\editor{Theo D’Hondt}
\editor{Wolfgang De Meuter}

\title

The command \title, as in amsart class, has two arguments: one optional, and one
mandatory:

\title[hShortTitlei]{hFullTitlei}

\subtitle

\author
\orcid
\affiliation
\email

The mandatory argument is the full title of the article. The optional argument, if present,
defines the shorter version of the title for running heads. If the optional argument is
absent, the full title is used instead.
It is expected that this command is inserted by the author of the manuscript.
Besides title, ACM classes allow subtitle, set with the \subtitle{hsubtitlei} macro.
The commands for specification of authors are highly structured. The reason is, they
serve double duty: the authors’ information is typeset in the manuscript, and is used by
the metadata extraction tools for indexing and cataloguing. Therefore it is very important to follow the guidelines exactly.
The basic commands are \author, \orcid (for the researchers registered with ORCID, http://www.orcid.org/), \affiliation and \email. In the simplest case you
enter them in this order:
\author{...}
\orcid{...}
\affiliation{...}
\email{...}

Do not use LATEX \and macro! Each author deserves his or her own \author command.
Note that some formats do not typset e-mails of ORCID identifiers. Do not worry:
metadata tools will get them.
Sometimes an author has several affiliations. In this case the \affiliation command should be repeated:
\author{...}
\orcid{...}
\affiliation{...}
\affiliation{...}
\email{...}

Similarly you can repeat \email command.
You may have several authors with the same affiliation, different affiliations, or overlapping affiliations (author A1 is affiliated with institutions I 1 and I 2 , while author A2 is
affiliated with I 2 only, and author A3 is affiliated with I 1 and I 3 , . . . ). The recommended
solution is to put the \affiliation commands after each author, possibly repeating
them:
\author{...}
\orcid{...}
\affiliation{...}
\affiliation{...}
\email{...}
\author{...}
\orcid{...}
\affiliation{...}
\email{...}

10

\author{...}
\orcid{...}
\affiliation{...}
\affiliation{...}
\email{...}

In some cases when several authors share the same affiliation you may try to save the
space using the format
\author{...}
\email{...}
\author{...}
\email{...}
\affiliation{...}

\additionalaffiliation

However, this format is not generally recommended.
In some cases too many affiliations take too much space. The command \additionalaffiliation{haffiliationi
creates a footnote after author’s name with the words “Also with {haffiliationi}”. You
should use this command only as the last resort. An example of usage is:
\author{G. Tobin}
\author{Ben Trovato}
\additionalaffiliation{%
\institution{The Th{\o}rv{\"a}ld Group}
\streetaddress{1 Th{\o}rv{\"a}ld Circle}
\city{Hekla}
\country{Iceland}}
\affiliation{%
\institution{Institute for Clarity in Documentation}
\streetaddress{P.O. Box 1212}
\city{Dublin}
\state{Ohio}
\postcode{43017-6221}
}

\position
\institution
\department
\streetaddress
\city
\state
\postcode
\country

Here Trovato and Tobin share their affiliation with the Institute for Clarity in Documentation, but only Ben Trovato is affiliated with The Thørväld Group.
The \affiliation and \additionalaffiliation commands are further structured
to interact with the metadata extraction tools. Inside these commands you should use
\position, \institution, \department, \city, \streetaddress, \state, \postcode
and \country macros to indicate the corresponding parts of the affiliation. Note that in
some cases (for example, journals) these parts are not printed in the resulting copy, but
they are necessary since they are used by the XML metadata extraction programs. Do
not put commas or \\ between the elements of \affiliation: they will be provided
automatically.
An example of the author block:

11

\author{A. U. Thor}
\orcid{1234-4564-1234-4565}
\affiliation{%
\institution{University of New South Wales}
\department{School of Biomedical Engineering}
\streetaddress{Samuels Building (F25), Kensington Campus}
\city{Sidney}
\state{NSW}
\postcode{2052}
\country{Australia}}
\email{author@nsw.au.edu}
\author{A. N. Other}
\affiliation{%
\institution{University of New South Wales}
\city{Sidney}
\state{NSW}
\country{Australia}}
\author{C. O. Respondent}
\orcid{1234-4565-4564-1234}
\affiliation{%
\institution{University of Pennsylvania}
\city{Philadelphia}
\state{PA}
\country{USA}}
\affiliation{%
\institution{University of New South Wales}
\city{Sidney}
\state{NSW}
\country{Australia}}

Note that old ACM conference formats did not allow for more than six authors and
required some efforts from the authors to achieve alignment. The new format is much
better in this.
Sometimes an author works in several departments within the same insitution. There
could be two situations: the departments are independent, or one department is within
another. In the first case just repeat the command \department several times. To handle
the second case the command has an optional numerical parameter. The departments
with higher numbers are higher in the organizational chart. Compare
\affiliation{%
\department[0]{Department of Lunar Studies} % 0 is the default
\department[1]{John Doe Institute} % higher than 0
\institution{University of San Serriffe}
\country{San Serriffe}}

and
\affiliation{%

12

\department{Department of Lunar Studies} % Not within JD Inst!
\department{John Doe Institute}
\institution{University of San Serriffe}
\country{San Serriffe}}

The command \affiliation formats the output according to American conventions. This might be wrong for some cases. Consider, for example, a German address. In
Germany postcode is put before city and is not separated by a comma. We can handle
this order using
\affiliation{%
\institution{Fluginstitut}
\streetaddress{Sonnenallee 17}
\postcode{123456}
\city{Helm}
\country{Germany}
}

However, the comma after postcode is unfortunate: the address will be typeset (in some
formats) as
Fluginstitut
Sonenallee 17
123456, Helm, Germany

To overcome this problem, the command \affiliation has an optional parameter
obeypunctuation, which can be false (the default) or true. If this parameter is true,
\afffiliation obeys the author’s command. Thus
\affiliation[obeypuctuation=true]{%
\institution{Fluginstitut}\\
\streetaddress{Sonnenallee 17}\\
\postcode{123456}
\city{Helm},
\country{Germany}
}

will be typeset as
Fluginstitut
Sonenallee 17
123456 Helm, Germany

\thanks

Note that you should not use this option for journals.
It is expected that these commands are inserted by the author of the manuscript.
Like amsart (and unlike standard LATEX), we allow \thanks only outside of commands

13

\authorsaddresses

\title and \author. This command is obsolete, and should not be used in most cases.
Do not list your acknowledgements and grant sponsors here: put this information in the
acks environment (see Section 2.9).
In some formats the addresses are printed as a footnote on the first page. By default
LATEX typesets them itself using the information you give it. However, you can override
its choice using the commmand \authorsaddresses{hcontact addressesi}, for example,
\authorsaddresses{%
Authors’ addresses: G.˜Zhou, Computer Science Department, College of
William and Mary, 104 Jameson Rd, Williamsburg, PA 23185, US;
V.˜B\’eranger, Inria Paris-Rocquencourt, Rocquencourt, France;
A.˜Patel, Rajiv Gandhi University, Rono-Hills, Doimukh, Arunachal
Pradesh, India; H.˜Chan, Tsinghua University, 30 Shuangqing Rd,
Haidian Qu, Beijing Shi, China; T.˜Yan, Eaton Innovation Center,
Prague, Czech Republic; T.˜He, C.˜Huang, J.˜A.˜Stankovic University
of Virginia, School of Engineering Charlottesville, VA 22903, USA;
T. F. Abdelzaher, (Current address) NASA Ames Research Center,
Moffett Field, California 94035.}

\titlenote
\subtitlenote
\authornote

You can suppress printing authors’ addresses by setting them to an empty string:
\authorsaddresses{}.
While the command \thanks generates a note without footnote mark, sometimes
the authors might need notes more tightly connected to the title, subtitle or author. The
commands \titlenote, \subtitlenote and \authornote that follow the corresponding commands (\title, \subtitle and \author) generate such notes, for example
\title{This is a title}
\titlenote{This is a titlenote}
\author{A. U. Thor}
\authornote{This is an authornote}

\authornotemark

Please never use \footnotes inside \author or \title commands, since this confuses metadata extraction software (actually these commands now produce errors).
Sometimes one may need to have the same footnote connected to several authors.
The command \authornotemark[hnumberi] adds just the footnote mark, for example
\author{A. U. Thor}
\authornote{Both authors contributed equally to the paper}
...
\author{A. N. Other}
\authornotemark[1]

\acmVolume
\acmNumber
\acmArticle
\acmYear
\acmMonth

The correct numbering of these marks is the responsibility of the user.
The macros \acmVolume, \acmNumber, \acmArticle, \acmYear and \acmMonth are
inserted by the editor and set the journal volume, issue, article number, year and month
corrspondingly. The arguments of all these commands, including \acmMonth is numerical, including \acmMonth, for example,

14

\acmVolume{9}
\acmNumber{4}
\acmArticle{39}
\acmYear{2010}
\acmMonth{3}

\acmArticleSeq

Note that \acmArticle is used not only for journals, but also for some conference proceedings.
The articles in the same issue of a journal have a sequential number. It is used to
vertically position the black blob in some formats. By default it is the same as article
number, but the command \acmArticleSeq{hni} can be used to change it:
\acmArticle{39}
% The sequence number will be 39 by default
\acmArticleSeq{5} % We redefine it to 5

\acmSubmissionID

Setting this number to zero suppresses the blob.
If you paper got a Submission ID from the Conference Management System, put it
here:
\acmSubmissionID{123-A56-BU3}

\acmPrice

The macro \acmPrice{hpricei} sets the price for the article
\acmPrice{25.00}

\acmISBN

Note that you do not need to put the dollar sign here, just the amount. By default
the price is $15.00, unless the copyright is set to usgov or rightsretained, when it
is suppressed. Note that to override the defaults you need to set the price after the
\setcopyright command to override the default. Also, the command \acmPrice{}
suppresses the printing of the price.
Book-like volumes have ISBN numbers attached to them. The macro \acmISBN{hISBN i}
sets it. Normally it is set by the typesetter, for example,
\acmISBN{978-1-4503-3916-2}

\acmDOI

Setting it to empty string, as \acmISBN{}, suppresses printing of ISBN.
The macro \acmDOI{hDOI i} sets the DOI number of the article, for example,
\acmDOI{10.1145/9999997.9999999}

\acmBadgeR
\acmBadgeL

It is normally set by the typesetter. Setting it to empty string, \acmDOI{} suppresses
DOI.
Some conference articles get special distinction, for example, the artifact evaluation
for PPoPP 2016 (see http://ctuning.org/ae/ppopp2016.html). These articles display
special badges supplied by the conference organizers. The class provides commands to

15

add these badges: \acmBadgeR[hurli]{hgraphicsi} and \acmBadgeL[hurli]{hgraphicsi}.
The first command puts the badge to the right of the title, and the second one—to the
left. The exception is the sigchi-a mode for SIGCHI Extended abstract, which puts
the badges on the left margin. The argument have the following meaning: [hurli], if
provided, sets the link to the badge authority in the screen version, while {hgraphicsi}
sets the graphics file with the badge image. The file must be a cropped square, which is
scaled to a standard size in the output. For example, if the badge image is ae-logo.pdf,
the command is
\acmBadgeR[http://ctuning.org/ae/ppopp2016.html]{ae-logo}

\startPage
\terms
\keywords

The macro \startPage{hpagei} sets the first page of the article in the journal or
book. It is used by the typesetter.
The command \keywords{hkeyword, keyword,. . . i} sets keywords for the article.
They must be separated by commas, for example,
\keywords{wireless sensor networks, media access control,
multi-channel, radio interference, time synchronization}

CCSXML
\ccsdesc

ACM publications are classified according to the ACM Computing Classification
Scheme (CCS). CCS codes are used both in the typeset version of the publications and
in the metadata in the various databases. Therefore you need to provide both TEX commands and XML metadata with the paper.
The tool at http://dl.acm.org/ccs.cfm can be used to generate CCS codes. After
you select the topics, click on “Generate CCS codes” to get the result like the following:
\begin{CCSXML}

\setcopyright

You need to just copy this code and paste it in your paper anywhere before
\maketitle.
There are several possibilities for the copyright of the papers published by ACM:
the authors may transfer the rights to ACM, license them to ACM, some or all authors
might be employees of the US or Canada Government, etc. Accordingly the command
\setcopyright{...} is introduced. Its argument is the copyright status of the paper,
for example, \setcopyright{acmcopyright}. The possible values for this command
are listed in Table 4.
The ACM submission software should generate the right command for you to paste
into your file.

17

\copyrightyear

Each copyright statement must have the year of copyright. By default it is the same
as \acmYear, but you can override this decision using the macro \copyrightyear, e.g.,
\acmYear{2016}
\copyrightyear{2015}

abstract
teaserfigure

There is a special case for a personal copy that the authors may be allowed to generate
for their use or a posting on a personal site (check the instructions for the specific journal
or conference for the details). The document option authorversion=true produces
the special form of the copyright statement for this case. Note that you still need the
\setcopyright command and (optionally) \copyrightyear command to tell TEX about
the copyright owner and year. Also, you should be aware that due to the different sizes
of the permssion blocks for the printed version and authors’ version the page breaks
might be different between them.
The environment abstract must precede \maketitle command. Again, this is different from the standard LATEX.
A special kind of figure is used for many two-column conference proceedings.
This figure is placed just after the authors, but before the main text. The environment teaserfigure is used for these figures. This environment must be used before
\maketitle, for example,
\begin{teaserfigure}
\includegraphics[width=\textwidth]{sampleteaser}
\caption{This is a teaser}
\label{fig:teaser}
\end{teaserfigure}

\settopmatter

Some information in the top matter is printed for certain journals or proceedings and suppressed for others. You may override these defaults using the command
\settopmatter{hsettingsi}. The settings and their meanings are listed in Table 5. For
example,
\settopmatter{printacmref=false, printccs=true, printfolios=true}

The parameter authorsperrow requires some explanation. In conference proceedings
authors’ information is typeset in boxes, several boxes per row (see sample-sigconf.pdf,
sample-sigplan.pdf etc.). The number of the boxes per row is determined automatically. If you want to override this decision, you may do it using this parameter, for
example,
\settopmatter{authorsperrow=4}

\received

However, in most cases you should not do this and use the default settings. Setting
authorsperrow to 0 will revert to default settings.
The command \received[hstagei]{hdatei} sets the history of the publication. The

for the subsequent ones. For example
\received{February 2007}
\received[revised]{March 2009}
\received[accepted]{June 2009}

\maketitle
\shortauthors

The macro \maketitle must be the last command in the top matter group: i.e., it
must follow the commands defined in this section.
After the command \maketitle the macro \shortauthors stores the names of the
authors for the running head. You may redefine it if the list of author’s name is too long,
e.g.,
\maketitle
\renewcommand{\shortauthors}{Zhou et al.}

2.4

Algorithms

There are now several good packages for typesetting algorithms [3, 4, 5], and the authors
are now free to choose their favorite one.

2.5

Figures and tables

New ACM styles use the standard LATEX interface for figures and tables. There are some
important items to be aware of, however.
1. The captions for figures must be entered after the figure bodies, and for the tables
before the table bodies.
2. ACM uses the standard types for figures and types and adds several new ones. In
total there are the following types:
figure, table: a standard figure or table, taking full text width in one-column formats and one column in two-column formats.
figure*, table* in two-column formats, a special figure or table taking full text
width.

19

teaserfigure: a special figure before \maketitle.
sidebar, marginfigure, margintable: in the sigchi-a format, special sidebars,
tables and figures on the margin.
3. Accordingly, when scaling the images, one should use the following sizes:
(a) For figure in one-column mode, figure* in two-column mode or teaserfigure—
\textwidth (in the one-column you can also use \columnwidth, which coincides with \textwidth in this case).
(b) For figure in two-column mode—\columnwidth.
(c) For marginfigure–\marginparwidth.
(d) For figure* in SIGCHI Extended abstracts—\fulltextwidth.
It is strongly recommended to use the package booktabs [6] and follow its main
principles of typography with respect to tables:
1. Never, ever use vertical rules.
2. Never use double rules.
It is also a good idea not to overuse horizontal rules.
For table footnotes you have several options described in TeX FAQ [1]. The simplest
one is to use \minipage environment:
\begin{table}
\caption{Simulation Configuration}
\label{tab:conf}
\begin{minipage}{\columnwidth}
\begin{center}
\begin{tabular}{ll}
\toprule
TERRAIN\footnote{This is a table footnote. This is a
table footnote. This is a table footnote.}

\end{center}
\bigskip
\footnotesize\emph{Source:} This is a table

20

sourcenote.
\emph{Note:} This is a table footnote.
\end{minipage}
\end{table}

sidebar
marginfigure
margintable

SIGCHI extended abstract extensively uses margin space. The package provides
three environments for this with option captions:
sidebar: textual information on the margin
marginfigure: a figure on the margin
margintable: a table on the margin
Tables and figures (including margin tables and margin figures) are by default centered. However, in some cases (for example, when you use several subimages per figure)
you may need to override this decision. A good way to do so is to put the contents into
a \minipage of the width \columnwidth.

2.6

Theorems

ACM classes define two theorem styles and several pre-defined theorem environments:
acmplain: this is the style used for theorem, conjecture, proposition, lemma, and
corollary, and
acmdefinition: this is the style used for example and definition.
These environments are defined by default. In the unusual circumstance that a user
does not wish to have these environments defined, the option acmthm=false in the
preamble will suppress them.

2.7
printonly
screenonly

Online-only and offline-only material

Some supplementary material in ACM publication is put online, but not in the printed
version. The text inside the environment screenonly will be typeset only when the option screen (see Section 2.2) is set to true. Conversely, the text inside the environment
printonly is typset only when this option is set to false. For example
\section{Supplementary materials}
\begin{printonly}
This section is included in the online version of the paper.
\end{printonly}
\begin{screenonly}
(The actual section).
\end{screenonly}

21

We use comment package for typesetting this code, so \begin and \end should start
at the first positions of the lines of their own (no initial spaces etc.).

2.8
anonsuppress

Note about anonymous mode

When the option anonymous is selected, TEX suppresses author information (including
number of authors) for a blind review. However, sometimes the information identifying
the authors may be present in the body of the paper
\begin{anonsuppress}
This is the continuation of the previous work by the author
\cite{prev1, prev2}.
\end{anonsuppress}

As for printonly and screenonly environments, \begin{anonsuppress} and
\end{anonsuppress} should start the line of their own (no leading or trailing spaces).

2.9

acks

\grantsponsor
\grantnum

Acknowledgments

The traditional “Acknowledgments” section is conventionally used to thank persons and
granting agencies for their help and support. However, there are several important considerations about this section.
First, in the anonymous mode this section must be omitted: it gives too much information to the reviewers. Second, the data about the grants is extracted and stored
separately by the postprocessing software. ACM classes provide facilities for both these
tasks.
The environment acks starts an unnumbered section “Acknowledgments” unless the
anonymous mode is chosen. Put all thanks inside this environment.
As for printonly and screenonly environments, \begin{acks} and \end{acks}
should start the line of their own (no leading or trailing spaces).
All the financial support must be listed using the commands \grantsponsor and
\grantnum. These commands tell the postprocessing software about the granting organization and the grant. The format of the command is the following:
\grantsponsor{hsponsorIDi}{hnamei}{hurli}
\grantnum[hurli]{hsponsorIDi}{hnumberi}.
Here {hsponsorIDi} is the unique ID used to match grants to sponsors, {hnamei} is
the name of the sponsor, {hurli} is its URL, and {hnumberi} is the grant number.
The {hsponsorIDi} of the \grantnum command must correspond to \sponsorID of a
\grantsponsor command. Some awards have their own web pages, which you can include using the optional argument of \grantnum command.
At present {hsponsorIDi} is chosen by the authors and can be an arbitrary key, in
the same way the label of \cite is arbitrarily chosen. There might be a change to this
policy if ACM decides to create a global database of sponsoring organizations.
Example:

22

\begin{acks}
The authors would like to thank Dr. Yuhua Li for providing the
matlab code of the \textit{BEPS} method.
The authors would also like to thank the anonymous referees for
their valuable comments and helpful suggestions. The work is
supported by the \grantsponsor{GS501100001809}{National Natural
Science Foundation of
China}{https://doi.org/10.13039/501100001809} under Grant
No.:˜\grantnum{GS501100001809}{61273304}
and˜\grantnum[http://www.nnsf.cn/youngscientsts]{GS501100001809}{Young
Scientsts’ Support Program}.
\end{acks}

2.10

\citestyle

Bibliography

ACM uses the natbib package for formatting references and the style ACM-Reference-Format.
bst for BibTEX processing. You may disable loading of natbib by using the option
natbib=false in \documentclass. However, it is not recommended, as well as the use
of BibTEX styles other than ACM-Reference-Format.bst, and may delay the processing
of the manuscript.
If you use natbib, you can select one of two predefined sitation styles: the authoryear format acmauthoryear or the numeric format acmnumeric using the command
\citestyle, for example,
\citestyle{acmauthoryear}

\setcitestyle

Note that numeric citations are the default mode for most formats.
You may further customize natbib using \setcitestyle command, for example,
\setcitestyle{numbers,sort&compress}

If you use natbib, then commands like \citep and \citeauthor are automatically
supported. The command \shortcite is the same as \cite in numerical mode, and
cites the year in the author-date mode.
There are several customized BibTEX entries and fields in ACM style ACM-Reference-Format.
bst you may want to be aware of.
The style supports fields doi and url, for example,
doi =
url =

"10.1145/1188913.1188915",
"http://ccrma.stanford.edu/˜jos/bayes/bayes.pdf",

The style supports arXiv recommended fields eprint and (optionally) primaryclass,
for example,
eprint =
"960935712",
primaryclass = "cs",

23

See the examples at http://arxiv.org/hypertex/bibstyles/.
There are special entries online and game for Web pages and games, for example,
@online{Thornburg01,
author =
"Harry Thornburg",
year =
"2001",
title =
"Introduction to Bayesian Statistics",
url =
"http://ccrma.stanford.edu/˜jos/bayes/bayes.html",
month =
mar,
lastaccessed = "March 2, 2005",
}

For these entries you can use the lastaccessed field to add the access date to the URL.
There are two ways to enter video and audio sources in the bibliograpy corresponding to two different possibilies. For standalone sources available on WWW you can use
an online entry, setting there howpublished field, for example,
@online{Obama08,
author =
"Barack Obama",
year
=
"2008",
title =
"A more perfect union",
howpublished = "Video",
day
=
"5",
url
=
"http://video.google.com/videoplay?docid=6528042696351994555",
month =
mar,
lastaccessed = "March 21, 2008",
}

For the sources available as attachments to conference proceedings and similar documents, you can use the usual inproceedings entry, again setting the howpublished
field:
@Inproceedings{Novak03,
author =
"Dave Novak",
title =
"Solder man",
booktitle =
"ACM SIGGRAPH 2003 Video Review on Animation theater Program",
year =
"2003",
publisher =
"ACM Press",
address =
"New York, NY",
pages =
"4",
month =
"March 21, 2008",
doi =
"10.9999/woot07-S422",
howpublished = "Video",
}

Sometimes you need to cite a complete issue of a journal. The entry periodical is
intended for this:

24

@periodical{JCohen96,
key =
"Cohen",
editor =
"Jacques Cohen",
title =
"Special issue: Digital Libraries",
journal =
"Communications of the {ACM}",
volume =
"39",
number =
"11",
month =
nov,
year =
"1996",
}

If you do not know the year of publication, the style will add “[n. d.]” (for “no date”)
entry.
If you do not know the author (this is often the case for online entries), use key field
to add a key for sorting and citations, for example,
@online{TUGInstmem,
key =
{TUG},
year =
2017,
title =
"Institutional members of the {\TeX} Users Group",
url =
"http://wwtug.org/instmem.html",
lastaccessed = "May 27, 2017",
}

2.11

Colors

While printed ACM publications are usually black and white, screen mode allows the
use of colors. The ACM classes pre-define several colors according to [7]: ACMBlue,
ACMYellow, ACMOrange, ACMRed, ACMLightBlue, ACMGreen, ACMPurple, ACMDarkBlue.
You can use them in the color assignments.
ACM provides the following recommendation on color use.
The most accessible approach would be to ensure that your article is still readable
when printed in greyscale. The most notable reasons for this are:
1. The most common type of inherited Color Vision Deficiency (CVD) is red-green
(in which similar-brightness colors that only differ in their amounts of red or green
are often confused), and it affects up to 8% of males and 0.5% of females of Northern
European descent.
2. The most common type of acquired Color Vision Deficiency (CVD) is blue-yellow
(including mild cases for many older adults).
3. Most printing is in Black & White.
4. Situational impairments (e.g., bright sunlight shining on a mobile screen) tend to
reduce the entire color gamut, reducing color discriminability.

25

Note: It is not safe to encode information using only variations in color (i.e., only
differences in hue and/or saturation), as there is bound to be someone affected!
To ensure that you are using the most accessible colors, ACM recommends that you
choose sets of colors to help ensure suitable variations in Black & White using either of
the following tools:
1. ColourBrewer: http://colorbrewer2.org/
2. ACE: The Accessible Colour Evaluator: http://daprlab.com/ace/ for designing
WCAG 2.0 compliant palettes.

2.12

Other notable packages and typographic remarks

Several other packages are recommended for specialized tasks.
The package subcaption [8] is recommended for complex figures with several subplots or subfigures that require separate subcaptioning. The packages nomencl [9] and
glossaries [10] can be used for the automatic creation of the lists of symbols and concepts
used.
By default acmart prevents all widows and orphans (i.e. lonely lines at the beginning
and the end of the page) and hyphenation at the end of the page. This is done by rather
strict settings
\widowpenalty=10000
\clubpenalty=10000
\brokenpenalty=10000

However, this may lead to frustrating results when the authors must obey a page limit.
Setting these penalties to smaller values may help if you absolutely need to.
Another problem might be the too strict line breaking rules. Again, a strategically
placed \sloppy command or putting the problematic paragraph inside sloppypar environment might help—but beware the results might be, well, sloppy.
Note that the uppercasing in section titles is done using textcase package [11], so
command \NoCaseChange inside title may help to prevent extraneous uppercasing.

2.13

A note for wizards: acmart-preload-hook.tex

Sometimes you need to change the behavior of acmart. The usual way to do this is
to redefine commands in the preamble. However, these definitions are executed after
acmart is loaded, and certain decisions are made. This presents a number of problems.
For example, one may want to use titletoc package with acmart. This package should be loaded before hyperref. However, since acmart loads hyperref itself,
the line \usepackage{titletoc} in the preamble will lead to grief (see http://tex.
stackexchange.com/questions/357265/using-titletoc-with-acm-acmart-style).
Another example is passing options to package. Suppose you want to use dvipsnames
option of xcolor package. Normally you cannot do this because acmart loads this package itself without options.

26

The file acmart-preload-hook.tex may be used to solve these problems. If this
file exists, it will be processed before any other package. You can use this file to load
packages or pass options to them. For example, if you put in this file
\let\LoadClassOrig\LoadClass
\renewcommand\LoadClass[2][]{\LoadClassOrig[#1]{#2}%
\usepackage{titletoc}}

then titletoc will be loaded before hyperref. If you put in this file
\PassOptionsToPackage{dvipsnames}{xcolor}

you will pass dvipsnames to xcolor.
Important note. This hook makes it too easy to create a manuscript which is not
acceptable by ACM. Even easier it is to create a file which cannot be compiled. So please
do not use it unless you know what you are doing. And if you use it, do not ask for support.
If you decided to use this hook, you are on your own.

Implementation

3.1

Identification

We start with the declaration who we are. Most .dtx files put driver code in a separate
driver file .drv. We roll this code into the main file, and use the pseudo-guard 
for it.
hclassi\NeedsTeXFormat{LaTeX2e}
h*gobblei

\normalparindent

amsart defines the \normalparindent length and initializes it to 12pt (the value of
\parindent in amsart). It is later used to set the \listparindent length in the
quotation environment and the \parindent length in the \@footnotetext command.
We set \normalparindent to the value of \parindent as selected by acmart for consistent paragraph indents.
549 \setlength\normalparindent{\parindent}

Footnotes require some consideration. We have several layers of footnotes: frontmatter footnotes, “regular” footnotes and the special insert for bibstrip. In the old ACM
classes bibstrip was a \@float. The problem with floats is that they tend to, well, float—
and we want the guarantee they stay.
We use manyfoot for layered footnotes instead.
\copyrightpermissionfootnoterule

This is the footnote rule that separates bibstrip from the rest of the paper. It is a full
width rule.

AMS uses generous margins for the lists. Note that amsart defines \leftmargin values for list levels at begin document, so we must redefine them in the same manner. Also,
note that amsart redefines enumerate and itemize environments with a \makelabel
command that uses \llap, so the \labelwidth value is (effectively) irrelevant; nonetheless, we follow amsart and set \labelwidth to \leftmargin minus \labelsep.

Typesetting top matter

Some of our formats use two column design, some use one column one. In all cases
we use wide title. Thus we typeset the top matter in a special box to be use in the
construction \@twocolumn[hboxi].
1494 \newbox\mktitle@bx

\maketitle

The (in)famous \maketitle. Note that in sigchi-a mode authors are not in the title box.
Another note: there is a subtle difference between author notes, title notes and
thankses. The latter refer to the paper itself, and therefore belong to the copyright/permission block. By the way, this was the default behavior of the old ACM classes.

Make acmplain the default theorem style.
2419 \theoremstyle{acmplain}

Delay defining the theorem environments until after other packages have been
loaded. In particular, the cleveref package must be loaded before the theorem environments are defined in order to show the correct environment name (see https://github.com/borisveytsman/acmart/iss
The acmthm option is used to suppress the definition of any theorem environments. Also,
to avoid obscure errors arising from these environment definitions conflicting with environments defined by the user or by user-loaded packages, we only define environments
that have not yet been defined.
