How To Use e-books by Format

Google eBooks
Once your purchase is complete, you will be directed to download your Google eBooks from your Account page, where your e-book files will be found on the My eBooks tab. From here, you can read your e-book in the web-based Google Books reader, or any device with the Google Books application.
You also have the option to Download an Adobe Digital Editions version of your Google eBook purchase, which can then be transferred to a Nook or Sony Reader mobile reader device (see Adobe Digital Editions instructions).

Palm
Palm format e-books can be read on any iPhone, iPad or iPod touch through the free eReader
application, which must be installed in advance of your purchase.  You can purchase and download the Palm e-book from our site through a mobile web browser. Once purchased, click the download link and the ebook will open automatically into the eReader application.
There is also an eReader desktop program, so these books can also be read on computers. Your customer can purchase and download the Palm e-book from your site on their computer, then open with the eReader desktop program.

Adobe Digital Editions
Adobe Digital Editions files are readable on a computer through Adobe’s free program also called Adobe Digital Editions. The Adobe Digital Editions software is required for using Adobe Digital Edition files. Adobe Digital Editions files are also compatible with the mobile e-reader devices Nook and Sony Reader, by transferring files to the appropriate device when connected to a computer. Here are the steps for each device:

The e-book files will download automatically after purchase into your default download location. Once the Adobe Digital Edition file is downloaded, double-click this file to open in the Adobe Digital Editions reader. At this point the book can be read on a computer through the Adobe Digital Editions reader.

Nook instructions:
Once plugged in, the Nook will appear as a device under the your Bookshelves. From here, you can simply drag and drop the ebook file from the Library to the device icon. Once the device is ejected, the purchased e-book will appear in the Nook’s inventory.

Sony Reader instructions:
Sony Reader users must also use Sony’s free Reader Library program to interface with their device. There are separate instructions for PC and Mac users.
PC users: Connect a Sony Reader device and open Reader Library. The device will appear in the Reader Library menu as Reader. Reader Library will ask the user to associate any EPUB files (which includes Adobe Digital Editions files) with Reader Library by default—if Sony Reader is the sole device the customer plans on using, choose yes.
Import files into Reader Library by choosing File > Import Files from the menu. Once the downloaded titles appear in the Library, you can simply drag the titles from the Library to the Reader. Once the device is ejected, the purchased e-book will appear in the Sony Reader’s inventory.

Mac users:
Connect your Sony Reader device and open Reader Library. The device will appear in the Reader Library menu as Reader. Reader Library will ask you to associate any EPUB files (which includes Adobe Digital Editions files) with Reader Library by default—choose no.
Import files by choosing File > Import Files from the menu. Rather than the default download location, the appropriate Adobe Digital Editions files will be found in Documents > Digital Editions. Once the downloaded titles appear in Library, the customer can simply drag the titles from the Library to the Reader. Once the device is ejected, the purchased e-book will appear in the Sony Reader’s inventory.
