BibTeX, biblatex and biber ⇒ Strange Depiction of References

[artyomje]

hello,

I am using TeXnicCenter, and I have a very strange problem.

Every time I convert the same source file to the PDF, the references are represented in a different (but a wrong!) way. What could be a reason?
Thank you in advance

Hi,

welcome to the board!

Please tell us in more detail what is strange and what do you mean by a different and wrong way. Wrong numbers, wrong font or appearance? Do you get any warning or error messages?

The best would be if you would post a reduced compilable example (minimal working example) which shows that wrong behavior. So we could see and fix it, instead of speculating about possible reasons.

Please see below an example (something very basic). There is a .bib file in the same directory. On the output, sometimes I see "?" in the text instead of citation, but there is a list of bibliography in the end . But when I convert the same file once again, I can see citation correct (in the Author(year) format), but no references list below...

Code: Select all

\documentclass[a4paper,12pt]{article}
\usepackage{natbib}
\begin{document}
....

\citet{nurmi1981problem} ....
\bibliographystyle{apalike}
\bibliography{PR}

\end{document}

On the output, sometimes I see "?" in the text instead of citation, but there is a list of bibliography in the end .

That's normal for a first run. In a first run the references are unknown. Then if BibTeX is run, and LaTeX again, references can be resolved and are shown.

But when I convert the same file once again, I can see citation correct (in the Author(year) format), but no references list below...

Could it be that your editor removes .aux or .bib/.bst files or generally auxiliary files after compiling? Some editors may have such a setting. Check if those files are there. Perhaps convert manually instead of using the editor.

thank you.
those files are on their place..

The warning I have is:"citation 'xxxx' is undefined on input line ..."
But when I use regular \cite command instead of \citet or \citep, everythin works good! So, I guess, my .bib file is correct, and so is editor. Why should natbib package change?

[Stefan Kottwitz]

natbib and apalike are compatible. The small code piece you showed above should be ok. Perhaps show a complete example with the problem, a hacked down minimal working example, compilable. That ensures that we could know all about the problem (if it's in the code, not in your TeX installation).

Thank you for your attempts to assist. I found the problem.
My .bib was built automatically by exporting from Google Scholar. In their bib. item form the field 'author' comes after the field 'title', and that makes problem when natbib is used.
