Internet Archive and an Open Library

The Internet Archive, a 501(c)(3) non-profit, is building a digital library of Internet sites and other cultural artifacts in digital form. Like a paper library, we provide free access to researchers, historians, scholars, the print disabled, and the general public.

 About the Project Open Library is an open, editable library catalog, building towards a web page for every book ever published. More Just like Wikipedia, you can contribute new information or corrections to the catalog. You can browse by subject, author or lists members have created. If you love books, why not help build a library?
