Funny you should mention Zecharia Sitchin. I was going to admit that he was the author of the "wacky" books in my library, but was kind of embarassed. I've actually read the entire "earth chronicles" series, and have an autographed copy of "The Cosmic Code". I saw one of his lectures in Baltimore in 1999, it was great fun. I've only perused Velikovsky's stuff at the library, but no kooky info library is quite complete without at least one work by Erich von Daniken.
