eBooks
The term eBook refers to an electronic version of a book. eBooks can be read using an eReader or on a variety of devices using software compatible with that device. The most important consideration when purchasing an eBook is what device you intend to view the book on.
ePub/Mobi eBook: ePub and Mobi eBooks will automatically adjust to fit your screen. These eBooks do not include page numbers, and the text reflows as the reader increases or decreases the font size. ePubs can be read on an eReader, your computer, or on an iOS or Android device using Adobe Digital Editions or other software you choose. Mobi eBooks can be downloaded and read on your Kindle device or by using the Kindle Previewer application on a computer.
PDF eBook: The PDF eBook has a static layout with set page breaks. This format is best viewed on a device with a large screen because the font size does not adjust to fit your screen like it does in the ePub and Mobi file. Although you cannot adjust the font size to fit your screen, you may zoom in on a page or image. The PDF eBook can be read on an eReader, your computer or on an iOS or Android device using Adobe Digital Editions or other software you choose.
The eBook format you choose must be compatible with your device or the software you wish to use. Click here for instructions on how to download software for your device.
The eBook format you choose must be compatible with your computer, handheld device, or eReader operating system, and the reader software you use.
