\maketitle

This package provides a style for \pkg{biblatex} which follows the
guidelines of the \textsc{aip} and \textsc{aps}. The citation style is numeric
and unsorted. The bibliography style follows the pattern of the official
REV\TeX{} class (\url{http://ctan.org/pkg/revtex}). The style should be loaded
in the usual way
\begin{verbatim}
  \usepackage[style=phys]{biblatex}
\end{verbatim}
Load-time options are provided to deal with the small number of variations
between the \textsc{aip} and \textsc{aps} styles.
The References section of this document demonstrates the format
generated by the package using the \texttt{biblatex-phys.bib} database
of example citations.

The styles use the standard \pkg{biblatex} database requirements. This means
that a database designed for traditional \BibTeX{} use may need some
editing for optimal output. The accompanying example database
\texttt{biblatex-phys.bib} shows examples of all of the supported entry types
with common fields filled in.

\section{Style options}

All of the styles here add a small number of package options to the standard
set provided by \pkg{biblatex}. This allows the styles to cover the variations
seen between the \textsc{aip} and \textsc{aps} styles.

\DescribeOption{doi}
\DescribeOption{eprint}
\DescribeOption{isbn}
\DescribeOption{url}
The standard style options \opt{doi}, \opt{eprint}, \opt{isbn} and
\opt{url}, as described in the \pkg{biblatex} manual. However, these
options are turned off as standard by the \pkg{phys} style. This reflects the
fact that these entries may be present in reference databases but are not
generally included in published bibliographies. Note that \textsc{doi} values
are printed for journal articles with no pages or eid given, even if the
\opt{doi} option is \opt{false}.

\DescribeOption{subentry}
In common with the standard \pkg{biblatex} numeric styles, all of the styles
in the bundle support the boolean \texttt{subentry} option. With this set
\opt{true}, entries of type \texttt{set} are given individual labels within
the bibliography.

\DescribeOption{articletitle}
The use of article titles varies between the \textsc{aip} and \textsc{aps}
styles. The boolean option \opt{articletitle} is available is control this
behaviour. The standard settings is \opt{true}, which follows the guidelines of
the \textsc{aip}: it should be set to \opt{false} to follow the \textsc{aps}
style. (This option also applies to the titles of proceedings entries and
patents, which are treated in the same way.)

\DescribeOption{biblabel}
The format of the numbers used in the bibliography (the \enquote{bibliography
label}) varies. The \opt{biblabel} option allows the user to easily set the
format used. This option takes a values \opt{superscript} (the standard
setting) and \opt{brackets}.

\DescribeOption{chaptertitle}
Printing chapter titles for \texttt{incollection} entries is part of the
\textsc{aip} style but is not part of the \textsc{aps} style. The
\opt{chaptertitle} option can be used to control this.

\DescribeOption{pageranges}
The inclusion of the full page range of journal articles varies between the
\textsc{aip} and \textsc{aps} styles. The boolean option \opt{pageranges} is
available is control this behaviour. The standard settings is \opt{true},
which follows the guidelines of the \textsc{aip} and prints the full range:
it should be set to \opt{false} to follow the \textsc{aps} style, which will
result in only the first page being printed.

\subsection{\texttt{collaboration} field}

To support large-scale collaborations, the style recognises the
\texttt{collaboration} field. This is a simple text field which gives the
name of the collaboration, and which is printed in parenthesis after the
authors.

\subsection{\textsc{aip} and \textsc{aps} styles}

As detailed above, the standard settings follow the \textsc{aip} style.
To obtain the \textsc{aps} style, use
\begin{verbatim}
  \usepackage[%
      style=phys,%
      articletitle=false,biblabel=brackets,%
      chaptertitle=false,pageranges=false%
    ]
    {biblatex}
\end{verbatim}

\section{Title formatting}

The style convert article titles to sentence case format. This can be
suppressed using
\begin{verbatim}
\DeclareFieldFormat{titlecase}{#1}
\end{verbatim}

\section{\textsc{url} formatting}

The style uses the \pkg{url} package to format hyperlinks. As such, the
format of these is left to the document author to alter. The \cs{urlstyle}
command may be used to alter this, either for the whole document or only
for the bibliography, for example by using
\begin{verbatim}
\AtBeginBibliography{%
  \urlstyle{same}%
}
\end{verbatim}

\section{Interaction with \pkg{babel}}

In common with other \pkg{biblatex} styles, \pkg{biblatex-phys} uses the
\pkg{csquotes} package mechanism to place article titles in quotation marks.
This means that the formatting of these will depend on the \pkg{babel}
language in use. Full details are covered in the manuals for \pkg{biblatex}
and \pkg{csquotes}.

\section{Errors and omissions}

database, found at
