I have a tough question. Our library has eBooks available to download. I downloaded an ePub book and a pdf book. I was able to download them to my computer (Windows), but I can't get them over to the iPad. I'm using Adobe Digital Editions, and I can read them on the computer easily enough. The instructions tell me to open that software, connect the iPad to the computer, and the iPad will show up under "Bookcases". Then you can drag and drop the book onto the iPad. But the iPad will not show up under "Bookcases". Does anyone have a work around for me?
