1. The author wants to make the e-book available as a free download.
2. The author wants to prevent people from sharing copies of the e-book on peer-to-peer networks.
3. The author wants to allow people permission to use and modify the e-book.

A Creative Commons license is designed so that the information is available for public use and modification. The author would want the book to be shared in peer-to-peer networks.
