Now, a more pressing problem. We have had an epidemic of missing DVDs from our collection--not in circulation, not late. About half were last circulated to students; many were inhouse bookings, and 7 (out of 28) were never circulated at all, meaning they were handed to customers without being recorded in our circulation system, or were stolen. I think it is pretty obvious we are dealing with an inhouse thief.
Has anyone ever dealt with a similar situation? And a related question: how often, and how, do you inventory your collections?
Thanks for any feedback.
