This is an extraordinarily well written history of the three phases of anti-Semitism that came out of the Western World -(I didn't know that)- and finally morphed into the current fourth phase during the course of the late 18th to early 19th centuries.

I got it from Adam Kaplan, and I consider it a must read.
