\documentclass{article}

Here is \cite{zipf}.
\emph{1st references}
\bibliographystyle{alpha}
\bibliography{abc}
\newpage
\emph{2nd references}
\bibliographystyle{plain}
\bibliography{xyz}
\nocite{*}
\end{document}
The problem is that, the pdf file contains two references list (1) All citation references from my 1st bib file, (2) All the BibTeX entries from my 1st bib file. The second BibTeX entries are not shown in the pdf.
