Connect your eBook reader to your computer.
Install Adobe Digital Editions (ADE) on your computer.
From your Bookshelf, use the Download drop-down menu to select a format for each eBook (for the best experience, we recommend Adobe EPUB or Open EPUB, though many eBook readers also support Adobe PDF and Open PDF), then select Confirm & Download.
If prompted, authorize your computer with a free Adobe ID (this is required for transferring protected eBooks). If you don't have an Adobe ID, you'll see a link to create one.
Downloaded eBooks should open in ADE. To transfer an eBook to your eBook reader, make sure you're in ADE's "Library View" (you may need to click the Library button in the upper-left corner to get there). From there, drag and drop the eBook into your eBook reader, which should appear on the left under "Devices."
Once you've transferred a library eBook, you can read it on your device just like any other eBook.
Note: During the transfer process, your eBook reader will be automatically authorized with the same Adobe ID you used on your computer.
