### 8.4. The chapterbibliography environment

To produce a separate bibliography within a chapter, use this package:

\usepackage{chapterbib}


At the point in your document where you want the chapter bibliography to appear, use this command if you are using the author-year citation style:

\begin{chapterbibliography}
…
\end{chapterbibliography}


If you prefer the numbered citation style, append an optional argument like this (assuming you have fewer than 99 references):

\begin{chapterbibliography}[99]
…
\end{chapterbibliography}
