references as a subsection

Question

I am working with a \documentclass{book} document. It contains several chapters which have very few references, so that I choose to provide them as \foonote(s). But I have a single chapter with many references. I am wondering if I can construct a subsection (or section), in the end of the chapter, which containst the references of this one. E.g.

\documentclass{book}

\usepackage[utf8]{inputenc}
\usepackage{lipsum}
\usepackage[french]{babel}
\usepackage[Lenny]{fncychap}
 \usepackage{caption}

 \frenchbsetup{StandardLayout=true}

 \usepackage{paralist}

 \usepackage{geometry}

 \usepackage[pdftex]{graphicx}
 \usepackage{fancyhdr}

\renewcommand\contentsname{Table des mati\`eres}

\usepackage[colorlinks=true,
   linkcolor=red,
   urlcolor=blue,
   pdftitle={Dossier de Candidature},
   pdfauthor={Dimitrios S. Anagnostou}]{hyperref}

\fancypagestyle{mainmatter-pages}{%
  \fancyhf{}% Clear header/footer
  \renewcommand{\headrulewidth}{0pt}% Remove header rule
  \renewcommand{\footrulewidth}{0pt}% Remove footer rule
  \fancyfoot[L]{\hyperref[ToC-first-page]{Jump to Contents}}
 \fancyfoot[C]{\thepage}
}
\let\oldtableofcontents\tableofcontents
\renewcommand{\tableofcontents}{%
  \clearpage
  \phantomsection% Place hyperlink marker
  \label{ToC-first-page}% Set \label for hyperlink
  \oldtableofcontents
}
\let\oldmainmatter\mainmatter
\renewcommand{\mainmatter}{%
  \clearpage
  \oldmainmatter
  \pagestyle{mainmatter-pages}%
}

\usepackage[affil-it]{authblk}

 \usepackage{pdfpages}
\setlength{\oddsidemargin}{.5cm} \setlength{\evensidemargin}{.5cm}
\setlength{\textwidth}{15cm} \setlength{\textheight}{21.0cm}
\setlength{\topmargin}{0in}

\newcommand{\M}{{\it Mathematica}}
\providecommand\Matlab{\textsc{Matlab}}

\newcommand{\FIG}[2]
{
\begin{figure}[!hbt]
\begin{center}
\begin{minipage}{0.85\textwidth}
\centering{\includegraphics[]{#1}}
\caption{\label{#1}\small{#2}}
\end{minipage}
\end{center}
\end{figure}
}

\parindent0pt  \parskip10pt

    \begin{document}

    \end{compactitem}

    \end{description}

    \section{First}
    \section{Second}
    \subsection{Références bibliographiques}

    \end{document}

How can I include the elements of bibliography inside the subsection called "Références bibliographiques"?

Thanks in advance.
