The main problem with correct placement of occult books is that once somebody reads enough of the book to figure out where to put it, they get eaten by a shoggoth or something.

This reminds me of Igor Stravinsky's trouble with copyright issues. International copyright law didn't protect The Firebird (a huge potential money-maker), and he put out a revised version of the Firebird Suite in 1945 largely to get a version under copyright. He had similar trouble with Petroushka, with the added twist that he had quoted music he heard street musicians playing which of course turned out to be the intellectual property of other composers (he was quoting popular songs and the songwriters weren't anonymous).
