There was an interesting discussion over at Boing Boing earlier about libraries and how they handle books on the occult.
Cecile Dubuis wrote a master’s dissertation for University College London titled “Libraries & The Occult.” I’ve only read bits of it,but the challenge she identifies is that occult books are, by their nature, anomalous and hard to categorize, much like the phenomena discussed in their pages. As a result, they are often unsearchable in the context of traditional library classification systems.
Sadly, the discussion wandered off into weird, symbolic arguments about Remote Viewing and whether or not it can be scientifically validated (short answer: it can’t. Remote Viewing has about as much science in it as Voodoo Economics has dolls and magic potions).
