If you want citations to work, but you don't want your bibliography to show up, try the following:
latex file.tex
bibtex file
comment out \biblography{} line
latex file.tex
If you latex again, it will screw up.
To make an independent bibliography, remove all text and replace all citep/citet/cite commands with \nocite{} in a different document. Remember to usepackage{natbib} etc. You may have to copy over the .bbl file.
