I need help. I am trying to open ebooks that I borrow at a public library site (elib.se) but they won't open in iBooks. They are downloaded in ePub format and I have eventually managed to transfer them to my iPad, they show up in my library but when I try to open them I am told that they can't be opened since they are in the wrong format. However, the Winnie the Pooh book opens nicely. According to the instructions at the library site it should work fine - does anyone have a clue?
