I downloaded a book from my regional library to Adobe Digital Editions on my PC, but when I connect the iPad to the PC, I have no link to transfer it to the iPad. It is an adobe ePub book which is supposed to be compatible with iPad. HELP!!
Adobe Reader for the iPad may work with Digital Editions. I'm not sure from the language of the App Store description. It talks about working with Livecycle rights management. I'm not sure how that relates to Digital Editions protection.
Two apps that are meant to work with the two library digital lending systems also support Digital Editions. It may take some finagling to get the files into the apps (I don't use either of them at this time), but it should be doable. There are other members here that are more familiar with them.
BlueFire Reader
Overdrive Media Console
In all cases the app will require you to sign in somewhere with the Adobe ID associated with that Digital Edition PDF. Check the developer's sites for details.
