Well Read?

We have certain books that never get checked out of the library but yet they have a lot of 'in-house' circulation counts.  Want to hazard a guess what the subject matter is?  It involves men dressing liking women.  Guess some people are curious but too embarrassed to check out certain material while others permanently borrow items that they feel are inappropriate for others to read like the Qur'an.  Don't know whether to blame the right-wing fanatics or the curiosity seekers on that front.  Every time there is a flare up in the right wing press all of our alternative religion books seem to disappear from the shelves.
