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, 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.

Most can also read eBooks in PDF, although PDF eBooks don't always display well on smaller screens.

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.
Our 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.
