Just thought I'd mention that the Cleveland Public Library is now "stocking" ebooks in the EPUB format. They are plugged as being "Sony Reader-compatible ebooks."
They are the first library to have ebooks available in the EPUB format (no doubt because Overdrive is based in Cleveland).
According to the PR, Overdrive expects to have "nearly every frontlist title from major publishers in EPUB, as they are—or soon will be—doing simultaneous release." Also, it looks like the NY and Chicago Public Libraries will be getting EPUB ebooks in the coming months, also.
My wallet thanks Amazon for not including Adobe Digital Editions and EPUB support in the kindle2. I cannot give up getting free ebooks from the library. Who would've thought that Sony would be producing a more open/compatible ebook reader than Amazon?
Library + Sony Reader = fantastic bargain
