What is the difference between the PDF access for E-book and hard copy reference guide purchases?

Answer

With each purchase of a hard copy 2009 Edition reference guide, 30-day access to a non-printable PDF version of the reference guide is available. Printable PDF versions of the reference guide are available for purchase independently of the hard copy.

The E-book purchase option provides 30-day access to download a printable PDF version of the reference guide. This option does not include a hard copy delivery of the reference guide. The E-book reference guides have a personalized water-mark on every page, which cannot be removed.

The PDF reference guides are intended for personal use only and should not be stored on any shared networks.
