Well, I read that iBooks can read the epub format, so I downloaded a couple from my library to my iMac. However, you need Adobe Digital Editions to read them on the computer and I can't find a way to make them work on the iPad. I know iBooks can read unencrypted epub format, but I am thinking that it is not possible to read the encrypted library books using epub. Does anyone know if there is another app or way to make them work on the iPad? I'm loving the iPad as a book reader, but sure would love to not have to buy every book. It seems crazy that some ereaders can use the encrypted epub books, while others can't. Thanks for the replies!
