\noindent
{\em SIGACT News}, the quarterly newsletter of the ACM Special
Interest Group on Algorithms and Computation Theory,
welcomes contributions
of interest to the international theoretical computer science community.
Contributions to {\em SIGACT News\/} will appear in the traditional
print newsletter and in the electronic newsletter
{\em SIGACT News Online} available to SIGACT members free of
charge at \url{https://sigact.org/SIGACT_News/online.html}.
The types of submissions encouraged include:

\begin{description}
\setlength{\itemsep}{-\parsep}

\item{\bf Letters to the Editor:}  Open letters that constructively contribute
to the interchange of opinions on issues of importance to
the theoretical computer science community.

\item{\bf Articles:}
Short survey or technical articles that provide general insights into, summaries of, or introductions to various subfields of theoretical computer science (technical papers that are more appropriate for refereed journals and conferences will, in general, not be printed in \emph{SIGACT News}); informational articles that describe initiatives that promote theoretical computer science or that inform readers of issues affecting the theoretical computer science community.  Humorous and satirical articles relevant to the theory community are especially welcome.

\item{\bf Transitions:}
Permanent and temporary changes of professional address
(these should include the duration, and
may include email address, telephone number, and fax number); eulogies and obituaries.

\item{\bf Regular Features:}
Suggestions (and volunteers) for new columns and other regular features
are welcome.  Suggestions for current columns should be directed
to the appropriate columnist.

\item{\bf Reports and Pictures:}
Submissions of reports with pictures from recent theoretical computer science professional meetings.

\item{\bf Book Reviews:}
Reviews of books of all sorts of interest to the SIGACT community.
Volunteers are welcome to review books in their area of expertise.

\item{\bf Conference Programs:}
Programs of forthcoming or recent computer science theory conferences.

\item{\bf Calls for Papers:}
Calls for papers and special issues of journals related to theoretical computer science.

\item{\bf Calls for Participation:}
Announcements of upcoming computer science theory conferences, including registration details.

\item{\bf Theory Calendar:}
Notices of upcoming events of interest to SIGACT members. These must be submitted to the
organizer of the theory calendar.

\item{\bf Announcements:}
Miscellaneous announcements of interest to the theoretical computer science
community.
\end{description}

\heading{Deadlines}

Deadlines for submissions are
\begin{center}
\begin{tabular}{ll@{\hspace{2cm}}ll}
{\em March issue:} &  February 1    & {\em June issue:} & May 1\\
{\em September issue:} &  August 1  & {\em December issue:} & November 1
\end{tabular}
\end{center}
Since many submissions to {\em SIGACT News\/} are time-sensitive, these
will be {\em hard\/} deadlines.
Submissions received after these deadlines
run the risk of being held over until the next issue.

To allow time for {\em SIGACT News\/} to be printed and mailed
to its subscribers,
submissions that publicize deadlines (such as ``Calls for Papers'' and
``Calls for Participation'')
should have that deadline fall no earlier than two months following
the submission deadline for {\em SIGACT News}.

\heading{Submission Procedure}

Submissions are required to be electronic, and, except as described above,
are to be e-mailed to the editor at {\tt editor.sigact@sigact.acm.org}.  Submissions will be acknowledged by e-mail. The following should be noted:

\begin{itemize}

\item
At a minimum, a source file in \LaTeX\ or MS Word format must be submitted, as the editor may need to make formatting adjustments to submissions directly in the source file.

\item
Where possible, a PDF version of the submission should accompany the source file for comparison purposes.

\item
In some instances, with the approval of the editor, PDF submissions may be made without accompanying source files.  In such cases, the formatting must be correct (see below) and all fonts must be embedded.

\item
Submissions in other formats require approval of the editor.

\item
Submissions of papers, articles, and columns should contain a picture of the author.  This is not a binding rule; the intent is to provide authors with more recognition and readers with a richer experience.  The picture should measure 2 inches (5 cm) high and 1.33 inches (3.33 cm) wide (this approximates the height:width ratio of many ``point and shoot'' digital cameras when held in the vertical position) and have a resolution of at least 300 pixels per inch.  The picture should be a head-and-shoulders portrait, and should be placed after the title and author information, and before the start of the paper, centered.  Snapshots are fine if cropped to obtain a portrait; there is no need to obtain a professional portrait. If there is more than one author, co-author pictures should be placed in a row at the same location left to right in order of the authors' names.

\end{itemize}

\heading{Format}

\begin{itemize}
\item
Submissions should be single spaced.

\item
Text should be rendered in 11 or 12 point type.

\item
The text area should be 6.5 inches (16.5cm) wide, and 9 inches (23cm) high, and should have 1 inch (2.5 cm) margins on all four sides.

\item
The text file should be prepared for printing on 8.5 by 11 inch paper.

\item
There should be no page numbers or other header or footer text in any of the margin areas.
\item
The first page should contain a copyright notice; a simple statement of the form
``Copyright \copyright\ {\tt <your name here>}, 2019'' is sufficient in the title area or as a footnote (use the \LaTeX\ symbol \verb"\copyright" or the sequence of three characters '(' c ')' in Word to get the ``\copyright'' symbol).

\item
Pictures are encouraged.  They should be placed appropriately within the text and have a resolution of at least 300 pixels per inch.

\item
Use of the \LaTeX\ style file (SIGACTNews.sty), available at \url{https://sigact.org/SIGACT_News/SIGACTNews.sty}, is recommended for \LaTeX\ authors.

\end{itemize}

\noindent
Special submissions may certainly deviate from this format if the presentation is part of the message.  Also, single-page ``Calls for Papers'' may deviate from this format.
