I did a trivial hack of \cite and \bibitem commands to make a check of
cited condition. It is available at:

 http://tug.org/~cvr/bibcheck.sty

which issues a warning to the terminal and log like:

  *******************************************************
   This bibitem [abc] with KEY [2] is NOT CITED
  *******************************************************

Also it writes a file \jobname.uncited which will look like:

  Bibitem [abc] with key [bib2] not cited
  Bibitem [xyz] with key [bib6] not cited

Hope this might be useful. The usage is:

 \usepackage{bibcheck}
