Illustrations from Old Books.

There's a great website I found inside digg which features old illustrations from old books. Most of the books featured are already in the public domain which makes them free for us to use. Bellow are some of the examples of illustrations from the 1900's. The site also carries a lot of scan images taken from images and engravings ( all open to them copyright free ).

The name of the website is easy to remember and tells you what site offers.
