And you can add free ePub titles to iTunes and sync them to the iBooks app on your iPad.
Project Gutenberg, abbreviated as PG, is a volunteer effort to digitize and archive cultural works, to “encourage the creation and distribution of eBooks.”Founded in 1971 by Michael S. Hart, it is the oldest digital library. 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 December 2009, Project Gutenberg claimed over 30,000 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.
This could be a big iPad investing incentive for schools (once they pay the $500 cost of entry) because classics still cost money to print and store, yet once you’ve paid for an iPad, you have a virtually unlimited amount of text for children to download.
