Why is my Email Address Required
This site uses Email to notify the administrator when someone adds a new book or updates information about an existing book. Email is also used when users have forgotten their password. If you use an invalid email address then the site will be unable to contact you if you have trouble logging-in. The member lists will never be sold to anyone and you will not be spammed as a result of signing up for this service.
If the book you are entering does not have an ISBN number, simply type in "NOISBN" and the site will generate a faux ISBN number.
