## 3 Organization of the Article

A Living Reviews article consists of distinct parts, of which at least some must be present in every article and marked up using the correct commands. This organizational scheme is called the article skeleton and encompasses the following parts:
• Title
• Abstract
• Keywords for the article
• Article body
• Section 1
• Subsection 1
• Subsection 2
• Going further section (optional)
• Section 2
• Acknowledgments (optional)
• References

The appropriate LATEX commands corresponding to these article skeleton parts are listed below:

\documentclass{article}
\bibliographystyle{LivRevRel}

\usepackage{}
\usepackage{epubtk}
\newcommand

\begin{document}

With the \usepackage command you can include additional style files, and with \newcommand you can define new macros. However, please keep in mind the caveats concerning nonstandard packages and macros mentioned in Section 2.

The style file for interfacing to the software used by Living Reviews in Relativity to process the article – epubtk.sty – should be included as last package. Note that epubtk.sty includes the hyperref package automatically.

\title{}

##### Author(s), …

\author{}

Please repeat information as needed if different institutions are involved, using the \and or \\ (\newline) commands between \epubtkAuthorData commands in the argument of \author.

Information about each author should be given as argument of a \epubtkAuthorData command to make it available for processing. This command requires four arguments:

#1
the author’s name given as First Initial Last,
#2
the author’s affiliation; (use \\ to separate lines),
#3
#4
the author’s homepage.

The last argument may be left empty.

\date{} (with an empty argument)
\maketitle

##### Abstract

\begin{abstract} Text of abstract…\end{abstract}

##### Keywords for the article

\epubtkKeywords{Keyword 1,}

The \epubtkKeywords command is defined in a Living Reviews style file. The argument is a comma-separated list of individual keywords.

##### Article body

\section{Title of Section}
\label{Section-label}

\subsection{Title of Subsection}
\label{Subsection-label}

The division of the article into sections should include an appropriate introduction and summary (or conclusion). Further recommendations for sectioning an article can be found in the online guidelines for authors.

Technical caveat: If possible, do not use any mathematical symbols or equations in section headings, as they may not translate correctly to HTML or PDF-bookmarks.

\subsection{Going further}
\label{Going-further-label}

At the end of major sections of the article, authors are encouraged to add a paragraph called “Going Further”, in which they have the opportunity to do the following:

• Make references to places where more detail or peripheral detail is to be found (in cases where there was no natural place to make such a reference in the main text).
• Evaluate and annotate references in a way that would be awkward in the text.
• Point out gaps in the research field, or natural next steps.

\section{Acknowledgments}
\label{acknowledgments}

As last section, the author is free to include acknowledgments.

##### References
If you do not use BibTEX, the bibliography is generated this way:

\begin{thebibliography}{999}

\bibitem{}

\end{thebibliography}

We ask authors to follow our style suggestions for citing references, and to add the document type to them using a TEX-comment: \comment{article}. The style is close to that of some other journals. Our chosen style is designed to help us process references automatically and to place them into our global reference database. This database is a key part of Living Reviews, so it is important that authors assist us by keeping to our specified style.

Further information on the reference style, and how to use BibTEX in a Living Reviews article is again available in the online guidelines for authors.

Please make sure that you keep the order of the article skeleton as shown above.

This form of the skeleton and the corresponding commands have also been used to create this template. We therefore recommend the authors to look at the PDF and/or LATEX version of the template (or already published Living Reviews articles in case of uncertainty about the structure of a Living Reviews document.
