The Google Print beta is live and usable today. I spent some time playing with it, and like it very much. You may search for an author, or for a book title. Search results inlcude thumbnails of the book's cover. When a book link is clicked, it leads you to the first page of the book that includes your search term. You may click on arrows to turn the pages. The books include the table of contents, index, bibliography, etc., as well as portions of the text.
I looked at the title Little House on the Prairie. The wonderful illustrations are included. There are links for sites selling the title, of course, but the books are the focus.
Very impressive. Very useful, with great potential, and it is fun to use. Will Google be able to keep this service alive for copyrighted material?
