Who Woulda Thunk It?

Excuse me while I vent, but someone has been stealing audio books! Who would steal items from a public library when these items may be borrowed for free? And it's not a matter of these items falling down behind the shelf or being misshelved--someone is taking the CDs from the case and putting the empty case back on the shelf! As a taxpayer this makes my blood boil! Okay, I'm stepping down from my soapbox...
