For example: in August of 2000, I searched for a book titled Applied Cryptography, because I wanted to learn more about cryptology, a subject studied by my friend and colleague Michael Huth (author of Secure Communicating Systems: Design, Analysis, and Implementation). Well, I went to Barnes and Noble and was told:
Customers who bought:
Applied Cryptography: Protocols, Algorithms, and Source Code in C, second edition by Bruce Schneier
also bought:
Secrets of Sexual Body Language by Martin Lloyd-Elliott
which kindasorta makes sense if one is a literal-minded computer geek (IOW, a likely buyer of the first book).
I only wish I'd been a big enough geek at the time to take a screen shot. :-D
