In addition to print editions, many of our titles are now available as digital e-books—PDF and Kindle. Which format is right for you?

• PDF is best for viewing on your computer (Windows or Mac) and offers the most universal compatibility. Most e-book readers will also let you view PDFs.
• The Kindle format (technically referred to as the "Mobipocket" format) is specifically for use with Amazon devices, including the Kindle e-book reader.
