"These were created from the free books available as part of Project Gutenberg. Of all eBook formats, I chose the epub standard because it's open and well-documented, it makes good use of existing standards, and the FBReader eBook reader program can read epub files. Most importantly, FBReader is the only eBook reader that I know can run on the OLPC XO laptop."
"Free ebook sites, already in iBook (ePub) format
I have posted a few of these in various places, but thought I would tie it together here. These are some sites that have FREE ebooks that are already in ePub format. They will import and read as is in iBooks."

"The iPad's iBooks application supports the standard ePub format as well as books you purchase through the iBooks store. This means that you can use the huge library of free eBooks available from Project Gutenberg & Google Books. You can also read eBooks purchased through other sources such as The Pragmatic Bookshelf. Simply drag any ePub books you download to iTunes and after you sync your iPad, those books will appear in iBooks."
