Google Books

I do use Google Books regularly for both home and work.  Although I have not purchased anything directly through accessing books through this search, I find it an extremely useful tool to determine if an item is still in print and available.  The bibiliographic information is helpful and the ability to preview the contents and limited sections of a book aide in the selection process for our library (a school library) so that you are not acquiring items sight unseen.  It gives me the ability to research what is available for each curriculum area of the school and get new ideas for the collection.
