Eric or others, do you know of any utility that converts a PDF and retains coding for where font or font-style changes? Or converts a web page with associated CSS and notes where font-style and HTML text block stops and starts? It seems that would be the starting point for recognizing citation entities. I've seen websites for FreeCite http://freecite.library.brown.edu/ and Parscit http://aye.comp.nus.edu.sg/parsCit/ through web searches, but don't know how close they got to the Grail before becoming legend.

If I understand your question correctly, then you have two problems to address: 1) converting PDF, Word, etc. files into plain text, and 2) marking up the result (which is a bibliography) into structure data. Correct? If so, then if your PDF documents have already been OCRed, or if you have other files, then you can probably feed them to TIKA to quickly and easily extract the underlying plain text. [1] I wrote a brain-dead shell script to run TIKA in server mode and then convert Word (.docx) files. [2] When it comes to marking up the result into structured data, well, good luck. I think such an application is something Library Land sought for a long time. “Can you say Holy Grail?"
