Many publishers require powerful copy protection for their eBook titles. In order for you to be able to purchase and download eBook titles that have been secured for distribution, you first need to activate your Adobe Reader. Just as a credit card typically must be activated by a bank before use, your Adobe Reader needs to be activated before you can purchase and read eBooks packaged for secure distribution.

To protect copyrights, publishers and authors establish their own guidelines for how much of their eBooks can be printed or copied. This means that these permissions will differ from book to book. Each ebook file has a differing level of encryption which is controlled by the author/publisher at creation. For example, a publisher might give users the ability to print several pages of a cookbook within a set period of time.  You'll see specifc settings for the Adobe title under the ebook description.
