How do we get on these lists?

My library gets all kind of catalogs, mostly for books and office supplies. Some weird stuff, but today was a complete WTF.

National Vanguard Books
A catalog of books for the discerning white supremacist. No joke. In addition to such sterling selections as Mein Kampf, The Turner Diaries (in Greek and German as well as English) and The Bell Curve, are selections for brainwashing your young Aryan.
Actual text for the entry promoting the Hardy Boys–The Mark on the Door:

“After a Mexican driving a hired motorboat almost collides with The Sleuth on Barmet Bay, Frank and Joe are drawn into a mystery. The Mexican, Pedro Vincenzo, has been selling worthless stock in a phony oil company to unsuspecting White Americans, and the key to putting him in prison is the testimony of a timid accountant, Elmer Tremmer. But the accountant has a Jew-like streak to his character. This excellent story highlights the differences between mestizos and Whites. It is the 13th book in the series, and it is a reprint of the original story published in 1927 not one of those liberal rewrites.”

Aaagh!
It’s not the blatant stuff that bothers me, it’s the racist spin put on books I’ve known and loved for years.

I know this is the unpleasant part of the job, watching people use the power of books for evil.

Where is Conan the Librarian when you need him?
