You may even want a signed book!
Called the “Google of rare books” by the Irish Times, BookFinder, a subsidiary of the popular AbeBooks, lets you do just that. You can choose “Any,” “New,” “Used/Out of Print,” “First edition,” and/or “Signed copy.” So, say you are looking for a signed copy of The Curious Incident of the Dog in the Night-Time, which can be in any condition. You put that in the “Title” box, and then you select the button next to “Any” and the check box next to “Signed copy.”
After selecting the correct title on the next page, a results page comes up with both new and used copies, sorted by price (low to high). It’s that easy!
However, searching for books on the Internet is not the only think BookFinder.com can do. There is also a “Buyback” page where you put in the ISBNs of the books you want to sell, and it tells you which sellers will give you the most money for your books. Pretty neat.
