"Works with TeX, generates .bib, pipelines LyX, great!!"
Many, many features allow sorting or searching against all attributes. Updates have links to external databases, and can grab the references in .ris format.
What seems to work best for archives is a single .bib file, but now mine is over 1000 items. Occasionally, it just winks out. There are some "quirks" with importing entries, but this process has been smoother on recent updates.
I used to edit .bib files in a text editor. BibTeX let me forget those days!
