It seems like it's all deception, secrecy, and censorship living in the heart of the US Empire, and Curtin's article only adds to that view.
This is an appropriate tongue-in-cheek cynical read about how Amazon goes out of its way to make it difficult for you to buy this explosive book entitled 9/11 Unmasked: An International Review Panel Investigation by David Ray Griffin and Elizabeth Woodworth. Looking at the website at this moment reveals that a paperback edition is "Temporarily out of stock". Anyway, Curtin encourages you to buy it directly from the publisher.

Also it may interest you to know about an ad for a book entitled How to Read Donald Duck by Ariel Dorfman and Armand Mattelart originally published in 1971 that satirically attacked US propaganda, and which met with censorship both in Chile and USA, is once again available. So, get it while you can! (Thanks go to an activist for alerting me to this.)
