anotherNYjew, a blog I like but wouldn't read with your browser, your eyes, or your daughter in the room, followed up this list, of "harmful books" with his own list of truly terrible reading material.
Now it's my turn.... in no particular order:
Dianetics, by L. Ron Hubbard
Treason: Liberal Treachery from the Cold War to the War on Terrorism by Ann "the blond vampire" Coulter
The Secret of Jewish Femininity, by Tehilla Abramov.
Anything with Fabio on its cover

Barney: Sharing is Caring by Mark S. Bernthal, June Valentine
The Great Betrayal: How American Sovereignty and Social Justice are Being Sacrificed to the Gods of the Global Economy by Patrick J. Buchanan

Stone Edition of the Chumash
We'll do a list of the best books shortly.
