Anyone ever heard of these guys?

I was at the bookstore yesterday and stumbled upon one of their works titled "Everything you know is Wrong" or something to that effect. I thought it would be an interesting book akin to "Lies my Teacher told me", which just talks about how history textbooks in the United States tend to sugarcoat many many things, like the first Thanksgiving and the Vietnam War and stuff of that nature. The synopsis on the back had some pretty funky things though, such as

"The U.S. had prior knowledge of the 9/11 attacks"

"People are getting Mad Cow Diseases all over America"

and similar stuff like that. The main proponent of all the information in these books seems to be a fellow by the name of Russ Kick. Anyways, I guess my question would be... has this company (or this author) ever published anything of validity? I guess I was just startled to see (what appeared to be) such a conspiracist text in a rather mainstream bookstore. But I guess that's not too uncommon these days.
