Project Gutenberg

Project Gutenberg (PG) is a volunteer effort to digitize and archive cultural works, to "encourage the creation and distribution of eBooks."[2] Founded in 1971 by Michael S. Hart, it is the oldest digital library.[3] Most of the items in its collection are the full texts of public domain books. The project tries to make these as free as possible, in long-lasting, open formats that can be used on almost any computer. As of November 2010, Project Gutenberg claimed over 34,000 items in its collection. Project Gutenberg is affiliated with many projects that are independent organizations which share the same ideals, and have been given permission to use the Project Gutenberg trademark.

Wherever possible, the releases are available in plain text, but other formats are included, such as HTML, PDF, EPUB, MOBI, and Plucker.
