There are a number of fantastic tutorials that people have put together to walk you through using your ebook readers. Below are two that I have found helpful.
OverDrive Digital Media Tutorials - Videos introducing the OverDrive service (downloadable ebooks, video, music, and audiobooks) and walking you through using the materials in detail
Loading books with Adobe Digital Editions on your Nook - Shows step by step what to do to get your ebooks onto your Nook. While this video says it is for the Nook, it covers the basic steps you need to take for most readers to use our ebooks.
