I want to make the eprint identifier show up in my bbliography entries. Where do I put the .bst files shown at the link above?

Anywhere in your latex path. If you don't know what that means, just search your file system for other .bst files and put them there. On my machine this would be /usr/local/texlive/2007/texmf-dist/bibtex/bst/ or /usr/local/texlive/texmf-local/bibtex/bst/. Your mileage may vary.

Thanks. Now, I can get the eprint field to appear but now for some reason the "title" field is not appearing in my pdf document even though I type it into the .bib file. How can I change that?
