While looking for a book on Amazon, I accidentally (really) found a book with the title Fuck this Book. Of course this caught my eye, so I read the description and found it actually sounded interesting (a la Postsecret, Found and Church Signs Across America).
I used the handy greasemonkey script to search my library's catalog directly from Amazon. I was surprised to see that my library had a record for the book, but it was In Cataloging - and has been for three years (there's got to be a story here, and I'm still trying to track it down [update: I asked around and learned the story, and the book has since, sadly, been deleted from our catalog]).
But this got me thinking: what other bad words are indexed in the library catalog? I ran some searches, and was surprised at the results. In my library's holdings alone, fuck has 12 matches and shit has 16 matches. I ran through a list of bad words, but most others also had non-bad meanings (pussy cat, Dick Cheney, etc).
I think it's important for libraries to provide unfiltered access to information, and not vilify a work or person because they violate a social taboos (besides, profanity is often in the eye of the beholder).
