You can contact us using our contact page with any questions, but we'll go ahead and offer some suggestions here about the only tricky part of using an e-book: getting it onto your device correctly.

Amazon Kindle

Download the MOBI-format file to your desktop. Connect your Kindle to your desktop with a USB cable. Your desktop will recognize the Kindle as another drive. Drag and drop your e-book to the Kindle's "documents" folder. It will now appear in your Kindle library (it may appear under "all items," not "books").

iPads and iPhones

Download the EPUB-format file to your desktop. Open iTunes and add the e-book to your books library. Sync your desktop iTunes with your iPad or iPhone.

As an alternative, add the free Kindle app to your iPhone or iPad, then download the MOBI format to your desktop or laptop. Open iTunes, and click on your iPad or iPhone under the "devices" heading in the left-hand column. Click on the "apps" tab in the top menu bar. At the bottom of the apps page, you will see the Kindle app under "file sharing." Click the Kindle app and add your MOBI file to the window on the right by using the "add" button or by dragging and dropping. Finally, sync your devices. (Your book may appear in the Kindle app library under the "all items" tab, not the "books" tab.)

Windows-based desktops and laptops

For Windows-based desktops and laptops, download the EPUB-format file and use Adobe Document Reader (a free download at or Calibre E-Book Manager and Reader (a free download at or any other EPUB reader in the same way you would any other e-book.

As an alternative, download the MOBI-format file to your Windows-based desktop or laptop and use the free Kindle reader software for PCs. Add the downloaded file to your Kindle-PC library.

Other readers

Other readers, such as the Sony Reader, require the EPUB format. Transfer the file from your PC to your reader as you normally do, probably using the USB cable technique applicable to Kindles.
