Great new tools for literature searching

I just found out about these tools - they need to be played with a bit, but I already found a bunch of papers that I didn't know existed -- check them out:

http://ligercat.ubio.org   (uses word clouds)

www.pubget.com   (gets pdfs)

http://etest.vbi.vt.edu/etblast3/  (text similarities)


http://gopubmed.org  uses semantics (context/relationship significance)

and for fun, check out the plagiarism database, and see if you have been plagiarised - entire papers are copied according to this database, all too often (of course its easier to publish if you just copy other people's work) http://dejavu.vbi.vt.edu/dejavu/

and finally an online list of multiple useful sites:
