\section{First section}
Using \texttt{biblatex} you can display bibliography divided into sections,
depending of citation type.
Let's cite! The Einstein's journal paper \cite{einstein} and the Dirac's
book \cite{dirac} are physics related items.
Next, \textit{The \LaTeX\ Companion} book \cite{latexcompanion}, the
Donald Knuth's website \cite{knuthwebsite}, \textit{The Comprehensive
Tex Archive Network} (CTAN) \cite{ctan} are \LaTeX\ related items; but
the others Donald Knuth's items \cite{knuth-fa,knuth-acp} are dedicated
to programming.
