\section{\BibTeX{} Databases}\label{sec:bib}

A \BibTeX{} database file is a plain text file with extension \textt{.bib}.
It consists of entries of the following form:\tikzmark{doc7}

\hskip .5\normalparindent\tikzmark{doc5}\hskip .25\normalparindent%
\begin{minipage}[t]{.325\linewidth}

\begin{verbatim}
	@<entrytype>{<key>,
	    <field> = <value>,
	    <field> = <value>,
	    <field> = <value>,
	    ...}
\end{verbatim}
\end{minipage}%
\hfill
\begin{minipage}[t]{.05\linewidth}
  e.g.
\end{minipage}%
\hskip .5\normalparindent\tikzmark{doc8}\hskip .25\normalparindent%
\begin{minipage}[t]{.525\linewidth}
\begin{mverbatim}
	@book{tolkien-hobbit,
	  author = {Tolkien, J. R. R.},
	  title  = {The Hobbit},
	  date   = {YYYY-MM-DD},
	  ...}
\end{mverbatim}
\end{minipage}
\begin{tikzpicture}[overlay, remember picture]
  \draw
	({pic cs:doc6}) ++(0,\baselineskip) coordinate (doc6)
	({pic cs:doc7}) ++(0,\parskip-\baselineskip) coordinate (doc7)
	({pic cs:doc5} |- doc7) -- ({pic cs:doc5} |- doc6)
	({pic cs:doc8} |- doc7) -- ({pic cs:doc8} |- doc6)
	;
\end{tikzpicture}

\tikzmark{doc6}\meta{entrytype} partially determines which fields are required and which optional.
\meta{key} is a unique identifier used in citation commands to reference the entry.
\meta{field} is the name of a database field and determines the expected format of \meta{value}.
\meta{value} is the value of the relevant \meta{field} for the entry.

\section{Biber}\label{sec:biber}

\begin{minipage}{.5\linewidth}
  \begin{verbatim}
	biber [options] file[.bcf]
  \end{verbatim}
\end{minipage}%
\begin{minipage}{.5\linewidth}
  \begin{verbatim}
  	biber [options] --tool <datasource>
  \end{verbatim}
\end{minipage}

By default, Biber reads a \filename{.bcf} and produces a \filename{.bbl} which \LaTeX{} needs to produce a document's citations and bibliography.
But Biber also has a powerful ‘tool’ mode.
The manual explains the details but \verb|biber --help| is a more comprehensible starting point.

To produce a document-specific \filename{.bib}:
\begin{verbatim}
	biber --output_format=bibtex --output_resolve <filename>.bcf
\end{verbatim}
