I want to add an extra paragraph into my bibliography section, under the title, before the first references.

Is this even remotely possible, or do I need to look for another way around?

I'm using the acmsmall.cls layout - my bibliography is currently built like this:

\begin{thebibliography}{}

%%%I want to add a statement here!

\bibitem{G}
Carretero, J., Isaila, F., Kermarrec, A. M., Taïani, F., \& Tirado, J. M.
(2012, June).
Geology: Modular georecommendation in gossip-based social networks.
In Distributed Computing Systems (ICDCS), 2012 IEEE 32nd International Conference on (pp. 637-646).
IEEE.

\end{thebibliography}


You can redefine \thebibliography to add the text before the list used; I defined \AddNote to typeset the text:

\documentclass{acmsmall}

\makeatletter
\def\thebibliography#1{%
\footnotesize
\refsection*{{\refname}
\@mkboth{\uppercase{\refname}}{\uppercase{\refname}}%
}
\list{}{
\settowidth\labelwidth{}
\leftmargin0pt
\itemindent -\bibindent
\itemsep2pt
\parsep \z@
\usecounter{enumi}%
}%
\let\newblock\@empty
\sloppy
\sfcode\.=1000\relax
}
\makeatother

\begin{document}

\AddNote{And here's the text that will be added to the bibliography, right after the title but before the first entry. We add some more text here.}
\begin{thebibliography}{9}
\bibitem{G}
Carretero, J., Isaila, F., Kermarrec, A. M., Taïani, F., \& Tirado, J. M.
(2012, June).
Geology: Modular georecommendation in gossip-based social networks.
In Distributed Computing Systems (ICDCS), 2012 IEEE 32nd International Conference on (pp. 637-646).
IEEE.
\end{thebibliography}

\end{document}


The code simplifies using a patch to the command:

\documentclass{acmsmall}
\usepackage{etoolbox}

\makeatletter
\patchcmd{\thebibliography}
{\list}
{}
{}
\makeatother

\begin{document}

\AddNote{And here's the text that will be added to the bibliography, right after the title but before the first entry. We add some more text here.}
\begin{thebibliography}{9}
\bibitem{G}
Carretero, J., Isaila, F., Kermarrec, A. M., Taïani, F., \& Tirado, J. M.
(2012, June).
Geology: Modular georecommendation in gossip-based social networks.
In Distributed Computing Systems (ICDCS), 2012 IEEE 32nd International Conference on (pp. 637-646).
IEEE.
\end{thebibliography}

\end{document}

• @gonzalo-medina i'd like to learn how substitute the \AddNote{} command with an environment AddHeader. Something like \begin{AddHeader} <header text> \end{AddHeader} instead of \AddNote{<header text>}. i read your thesis about background and fancypar packages but i can't do it. – skpblack Jul 14 '14 at 1:28
• @skpblack feel free to open a fresh new question as a follow-up to this one. – Gonzalo Medina Jul 14 '14 at 14:45

An alternative, should you be using biblatex is to either print the bibliography without a heading and make your own heading and note:

\section*{References}
This note will appear before the bibliography...

...or use the prenote=... option with a \defbibnote to define your note.
\defbibnote{intro}{This note will appear before the bibliography...}
