TeXworks ⇒ Bibliography Problems

[edstevens]

I know that I am supposed to reproduce the code of a problem, but I am having problems even generating a reproduction.

I had to re-install my operating system due to a Windows crash. I managed to recover my documents but can't get my working paper in Latex to compile correctly.

The error looks like this:

Code: Select all

("C:\MyArticle.bbl"
! Undefined control sequence.
<argument> \protect \citeauthoryear 
                                    {Smith}{Smith...
l.4   Smith}{1999}]{Smith98}

I opened up C:\MyArticle.bbl and it looks like this:

Code: Select all

\begin{thebibliography}{}

\bibitem[\protect\citeauthoryear{Smith}{Smith}{1999}]{Smith98}
Smith (1999).
\newblock Article name article name.
\newblock {\em Journal Journal\/}~{\em 89}, 605--618.

\end{thebibliography}

In previous, working versions, C:\MyArticle.bbl looked like this:

Code: Select all

\begin{thebibliography}{10}

\bibitem{Smith98}
Smith
\newblock Article name article name.
\newblock {\em Journal Journal}, 89:605--618, 1999.

\end{thebibliography}

So it looks like TeXworks inserted the extra \protect\citeauthoryear tags. How can I get the bibliography when it compiles back to the old state, or get TexWorks to read the \protect\citeauthoryear tags?

Thanks!

Make sure to have an updated TeX-distribution, delete all the auxiliary files and try again.

Right now, it is impossible for me to see a reason for the behaviour described for a lack of information.

Hi Ed,

welcome to the forum!

It seems that \citeauthoryear is undefined. This is a command of the natbib package. So ensure that you are loading natbib, if not existent add this line to your document preamble:

Code: Select all

\usepackage{natbib}

Dear Stefan_K,

I could kiss you right now! Your recommended solution worked perfectly. Amazing how a little knowledge can shortcut hours of frustration.

Thanks so much.
