public domain information

I'm not exactly sure what you're asking for...


The Gutenberg Project has an incredible amount of public domain works for the picking... http://www.gutenberg.org/wiki/Main_Page
The Internet Archive is also another source of public domain works (even audio and video files as well)... http://www.archive.org/index.php
http://www.archive.org/details/texts

Google Books is the latest project to feature vast amounts of public domain materials but I'm not sure how they work as they also have volumes and volumes of nonpublic domain works as well...
