I have the same Nook and a bunch of PDF magazines. I know it's silly but I never liked the way the covers don't show up so I paid for a PDF reader, ezPDF Reader Pro. Now, my magazines show up on shelves with their covers fully intact. The downside is: I can't organize the magazines on the shelves, except by most recent read/opened. For me, that's not a big deal but you might want to look into the capabilities of other similar apps. I haven't found any other people who have been successful in getting the covers to show and loading magazines onto shelves. If you find out, please let me know. Thanks. Hope this helps.
