Depends, I suspect at least some of the uploads here were done so with the shorter Canadian Copyright. Can a library in the USA legally lend those out as Ebooks?
Better yet for a fairly minimal sum I believe that Project Gutenburg will burn disks of ebooks.

"Project Gutenberg periodically generates CD and DVD image files (ISO files) containing books from the collection. When downloaded, they can be used to make a CD or DVD using a CD or DVD writer. Please copy and give away these CDs and DVDs! Keep one for yourself, and give one to a friend … or a library … or a school. "
The July 2006 DVD contains over 17,000 books from our first 19,000 titles.
That would be a very easy, low cost way for any Library to get started with Ebook's.
