JabRef is a cross-platform BibTeX reference manager. I use it to manage my references for my research, not only because BibTeX is my preferred format, but also for the added features such as keeping track of my pdfs.
JabRef exports to a wide range of different formats, and also allows one to write custom export filters. I have written several export filters for HTML pages. The main features lie in the JavaScript to search and view the references.
