Leslie, I borrow a lot from NYPL. You must first open the book on your PC/Mac using Adobe Digital Editions. And the first time you open it on your eDGe, you should have Internet connectivity. I sometimes have to attempt to open the file several times before it actually opens. (I'm assuming you have library privileges/valid library card or you wouldn't be able to download the book.) After that, you can open it without being on the net.
