Hi Jed, The database/searching is looking good. Have you tried adding full text search? (Searching for "alumina powder" returns no hits, even though some of the PDF's use that term. Extracting the text from the pdf and adding it to the database can be automated.)
What database fields are available for the library? If you open the database and ftp/html/php to a number of trusted developers, you could probably get some really interesting results... Some additional fields that could be useful: Full text extracted from source Language Citations (list of references that ) Followers (list of people who like the paper) Discussion or wiki for the paper (vbulletin style?) Format(s) (HTML, PDF, PPT, etc) Some kind of Rating system Major categories (Ni-H, Pd, bubble, etc.) Maybe add a discussion or request section where users/researchers can put in what would be helpful to them.. Little changes like adding a COUNT(author) link that would display the other (N) papers written by any given author.. just takes a good php developer a few minutes to add each feature.. Developers who produce custom query/search pages could run them by you and the good ideas could be merged into the final product.. (As far as WordPress goes.. I'm not a huge fan, but its cheap and the plug-ins are plentiful.) - Brad
