Book Searching Page Added

I've been meaning to add a page to help keep track of some of the book search engines -- those that search the full text of digitized books, not book store searches -- and now I have finally added a book searching page. You can also view my presentation on book searching that I gave last week at the Computers in Libraries 2007 conference in DC. I plan on expanding the analysis and trying some more in-depth comparisons of these tools in the future.
