# Bibliography using Texshop and Mendeley export

Latex does not seem generate any bibliography. I use the minimal working example:

\documentclass{article}
\begin{document}
\bibliographystyle{plain}
\citet{Blavatskyy2011}
\bibliography{library}
\end{document}


The error I get is:

Undefined control sequence.


The library.bib file is in the same directory as the .tex file. I use TexShop on Mac OS X, the .bib file is created with Menedeley. The exemplary entry is:

@article{Blavatskyy2011,
author = {Blavatskyy, Pavlo R.},
doi = {10.1287/mnsc.1100.1285},
file = {:Users/Chris/Desktop/Mendeley Desktop/2011\_Blavatskyy\_A Model of Probabilistic Choice Satisfying First-Order Stochastic Dominance\_Management Science.pdf:pdf},
issn = {0025-1909},
journal = {Management Science},
keywords = {2010,2011,accepted october 19,advance january 28,by peter wakker,decision analysis,first-order stochastic dominance,history,online in articles in,probabilistic choice,published,random utility,received march 8,strong utility},
month = mar,
number = {3},
pages = {542--548},
title = {{A Model of Probabilistic Choice Satisfying First-Order Stochastic Dominance}},
url = {http://pubsonline.informs.org/doi/abs/10.1287/mnsc.1100.1285},
volume = {57},
year = {2011}


What could be the problem? The Mendeley export? TexShop? Other?

You don't say which control sequence is undefined, but the problem is likely that you don't load the natbib package. The \citet command is not defined by the LaTeX-core, so I guess that is the control sequence which is undefined. Hence, add

\usepackage{natbib}


to the preamble.

You should also change the \bibliographystyle to plainnat, which is natbibs version of the plain style.

• Also plain should be plainnat – egreg Feb 19 '14 at 23:28
• Thanks, the code is now: \documentclass{article} \usepackage{natbib} \begin{document} \bibliographystyle{plainnat} \citet{Blavatskyy2011} \bibliography{library} \end{document} The error message in the .log file is: Package natbib Warning: There were undefined citations – 360McTwist Feb 19 '14 at 23:40
• Does the .bib file entry look as it should? – 360McTwist Feb 19 '14 at 23:43
• Did you run bibtex after running latex (and after that you have to run latex twice). – Guido Feb 19 '14 at 23:51
• By the way in the bibtex example you must have a closing } at the end. I assume it is a problem with cut and paste. – Guido Feb 19 '14 at 23:53
