Actually, I think our worst problem is with our 'volunteer' shelvers who don't always get it right even with the training vid they have to watch LOL!

I'm wondering if they'll go with bar-coding or chipping to keep track electronically. We bar-code on the front now, but if it was small enough bar-code for the spine, you could easily run a scanner over a whole shelf to find stuff fast.

We have heard about book drops that sort by genre and automatically put all the fiction, children's, non-fic, etc. into a specific cart/holder. Of course, our remodel won't be that advanced.
