After two hours last night trying to get the protected book to my ipad to read I am so very grateful to find the app Blue Reader. WOW! It was so easy. I am an idiot with computers but their step by step help section for transferring library books was a synch. just download the app. go to the help section and you will see the section on how to transfer. Good luck
Sorry It is Blue Fire Reader.
Seriously thought that Adobe would have been on top of it already and worked in the ipad/itouch to the program.
