Bibtex

[Vergil83]

Can anyone explain bibtex to me? I have a small .bib file (2 entries) and a sample latex file (1 line with 2 in text cites). When I make the pdf from latex (pdflatex file), it will make it fine, except in text cites dont' work. However, the references will be listed in the bibliography. I then run bibtex file. If I then run pdflatex file again, the in text cites appear, but they occur twice and I get errors. I can't run bibtex file before, since it requires the .aux file.

My bigger question is, what the hell is bibtex doing. My naive assumption was that when the pdf was made, everything was read from the .bib file. However, it appears to be much more complicted. Also what is the difference between a .sty file and the .bst file, do I need both?

Ok, well I still don't understand how bibtex works, but I fixed my problem. I needed to include

\usepackage{natbib}

along with my .sty and .bst files
