I know that *I* don't have the rights to read that PDF, and I suspect you don't either. Do you have written permission from the copyright holder, Pearson Publishing, to download that ? I see a statement embedded in the work that permission is required to reproduce, store, transmit, etc in any form. Your suggesting on a public forum such as this that a random copy on a random website is an acceptable source of a copyrighted work is immoral and wrong. -- john r pierce 37N 122W somewhere on the middle of the left coast
