Is it using Overdrive? If so, yes, it is possible! I just checked out my first library book yesterday. It was super easy. You have to have Adobe Digital Editions installed on your computer, and register that with Adobe. Once you do that, when you're ready to check out a library book, when it gives you the option to download, just have it open with ADE. Also, you need to register your Pocket Pro with ADE, before you can put it on your Pocket Pro. To do that, you just open ADE (once you've registered - it's free), then connect your Pocket Pro to your computer. It will detect the device, and just follow the instructions. Then when you're ready to load your library book, you just click and drag it to the Pocket Pro, within ADE. The Pocket Pro will be listed on the left, with the bookshelves. I think that's what ADE calls them... anyway, if you have any other questions, there are a lot of people here who can help you out!
