I am facinated by banned books, mostly because they serve as a dip stick into the crazy morass of evolving societal values. Catcher in the Rye seems tame these days, but was banned in its time. The AD&D rule books were also banned in some communities (and probably served as the spark of this morbid facination).
So when boing boing ran a post about the Golden Book of Chemistry Experiments as part of its ongoing charting of the history of the war on fun, and indicated that it was banned. I had to find a copy.
