# How do I print the cite key along with the entire .bib file?

I am trying to print an entire *.bib file. I would like to print the citation key along with all the entries in the .bib file. I can print my bibligraphic data file (.bib) but cannot get it to print my cite key. I can use BibTeX or biblatex. Any ideas how to do this?

Here is a clearer explanation:

My MCMC.bib file contains:

@ARTICLE{Ait04,
author = {Y. A\"{i}t-Sahalia},
title = {Disentangling Diffusion from Jumps},
journal = {Journal of Financial Economics },
year = {2004},
volume = {74},
pages = {487-528}
}

@ARTICLE{Ait02,
author = {Y. A\"{i}t-Sahalia},
title = {Maximum-Likelihood Estimation of Discretely-Sampled Diffusions: A Closed-Form Approximation Approach},
journal = {Econometrica },
year = {2002},
volume = {70},
pages = {223-262}
}


I use the following LaTeX file:

\documentclass[12pt]{article}
\usepackage[style=verbose,citestyle=alphabetic,sorting=nty,natbib=true]{biblatex}
\bibliography{MCMC}
\begin{document}
\nocite{*}
\printbibliography
\end{document}


I would like the output file to contain the cite keys Ait04 and Ait02 at the start of each citation so that I know what key I have assigned to each citation. Any help would be most appreciated.

Welcome to TeX.sx! A tip: If you indent lines by 4 spaces, they'll be marked as a code sample. You can also highlight the code and click the "code" button (with "{}" on it). Also, I think you're using BibTeX and biblatex in your example; simply put, biblatex as a front-end and BibTeX as a back-end. For more information on the two, see tex.stackexchange.com/q/25701/4012. Besides, kudos for your MWE! For .bib files, the filecontents environment is useful. –  doncherry Apr 8 '12 at 8:34

The showkeys package might do just what you're looking for:

\documentclass[12pt]{article}
\usepackage[style=verbose,citestyle=alphabetic,sorting=nty,natbib=true]{biblatex}
\begin{filecontents}{MCMC.bib}
@ARTICLE{Ait04,
author = {Y. A\"{i}t-Sahalia},
title = {Disentangling Diffusion from Jumps},
journal = {Journal of Financial Economics },
year = {2004},
volume = {74},
pages = {487-528}
}
@ARTICLE{Ait02,
author = {Y. A\"{i}t-Sahalia},
title = {Maximum-Likelihood Estimation of Discretely-Sampled Diffusions: A Closed-Form Approximation Approach},
journal = {Econometrica },
year = {2002},
volume = {70},
pages = {223-262}
}
\end{filecontents}
%\bibliography{MCMC}
