Google Book Search is out and is pretty cool. I love the book previews and the links to all the places to purchase the book. Goodness, I did a search for "photoshop tips" and found a book called "1001 Photoshop tips" and it looks to me like I can almost read the entire book online! All 1742 pages of it! Cool!
It was in beta on January 30, 2007 when I first shared this.
In 2017, I have had a lot of success in finding ancestors in genealogy research here!
