Google Books | May 27th, 2007
Today I was looking up information for SpamAssassin. A google search brought me to Google Books. It is pretty cool. you search for a subject and it brings back all the books they have on it. Some of them have a limited preview of the book, others have the full text. Once you click on a book you just flip through the pages like you would on a normal book. You can also have google search the book for you.
