# Bibliography undefined errors

This is a working example that provides multiple error messages including that it couldn't find the authors. It doesn't accept any style format, including apastyle.

• Please, don't post picture of your output, but include it as text. Your MWE also compiles fine, your error is not reproducible. Aug 17 '16 at 12:43
• You have a & in one of your entries ("Thames & Hudson"). Try replacing it with \&, as & is special to LaTeX. Aug 17 '16 at 12:43
• I just replaced it. Now, the roar message in bibtex is: I'm skipping whatever remains of this command I found no style file---while reading file

• Why only the last? If the error occurs in the third step, you even don't need to include the fourth step. I still cannot reproduce your problem. Please add a working MWE. You could also update your question with your current error message - your last comment is not really meaningful. Aug 17 '16 at 12:54

There is no apastyle bibliography style. This is what the message

I couldn't open style file apastyle.bst

tells you. However, there is apalike, which works with your example. So, replace

\bibliographystyle{apastyle}


with

\bibliographystyle{apalike}


You should also make sure that you reference the correct file with \bibliography. You say \bibliography{bib}, but bibtex says there is no such file:

I couldn't open database file bib.bib

• Yes, you are correct. apastyle was the problem. Thank you.
