We offer many of our books in EPUB and PDF formats. EPUB is a format compatible with many smartphones and eReader devices, including Amazon Kindle. PDFs can be opened on any Mac or PC with the free Adobe Reader software (or Adobe Digital Editions if the PDF is protected with Digital Rights Management software), as well as on many smartphones. Most of the eBooks we offer can be viewed on more than one device. If you download the eBook file to your computer, you can then copy it to a portable eReader, Kindle, Nook, Android phone or tablet, iPhone or iPad, or another smartphone. Keep reading for more information on which format is best for you.

Most tablets and eReaders (including the iPad, Kindle, and Nook) and smartphones (including the iPhone and Android) can read eBook files in the popular EPUB format. Most can also read eBooks in PDF, although PDF eBooks don't always display well on smaller screens. To the right you'll see links to specific instructions for using our eBooks on the most popular eReaders and smartphones.
If versatility is important to you, choose the EPUB version of a book when available; it's compatible with almost all devices and will look best on the screen of your specific device.
If page fidelity is important to you, choose the PDF version of a book; it exactly reproduces the original printed page and can be viewed with the popular Adobe Reader software on many devices.

Can I Share My eBook Files?
When you purchase an eBook, that copy is designed for your own personal use. While you can copy an eBook file for use on another device you own, such as a portable eReader or smartphone, you cannot share copies with other people. You also cannot sell used eBooks; ownership is yours only, and cannot be transferred.
Most of our eBooks are sold without DRM and can easily be copied to up to six devices. You cannot share these eBooks with other people, however. Our non-DRM eBooks are embedded with personalized watermarks that help us identify any unauthorized copies found online. For more information on watermarking, see our Watermarked eBook FAQ.
To protect against unauthorized copying, some of the eBooks we sell as PDFs include digital rights management (DRM) technology. This technology limits the use of the purchased eBook(s) to a maximum of six devices. Adobe Digital Editions is required to view these DRM-protected files.
