Is Google print an early version of this? I just did a search and it brought up some books that had information on the subject I'm doing. I think the entire book was online and I needed my Gmail account to login to it.
It was great... took me to the page of the book that had the words I searched for and I can reference it in my assignment as being a book not a web site.
This is something I wasn't expecting but I like were its headed now (for research).
