Providing the entirety of CofC to you personally while it is copyrighted would be no problem provided Amazon.com et al refused to sell you a copy on the grounds that you are attending meetings of Jehovah's Witnesses and you are in good standing. I think that it would thus pass the test for Fair Use that requires copying not to obstruct the copyright holder from distributing more of the product.
As the Watchtower restricts to whom they will 'sell' the CD, someone providing a copy to a bloodthirsty apostate doesn't cut into their sales. Besides, I'm talking about mailing something from one person to another, not making it available to an unlimited number of people on the Net.
Of course a sample chapter of CofC might have the effect of whetting appetities and result in sales for the author, much like cheese on toothpicks or automobile test drives. Thus the author has given permission for Chapter 1 to be online at http://www.commentarypress.com/eng-crisis-ch1.html.

Edited becaue I made a good point in paragraph 2 about limited vs. unlimited distribution availability and decided it was better to say "to you personally" rather than "online."
