I work in a joint-use library, so we're part community college, part public. I went to a meeting at another public branch last week, and I got to see their AMH! We have one too (they put one in our brand-new building to see if they liked it before they started adding it to the other branches). AMH stands for Automated Materials Handling, and it's the system that automatically checks in your books when you put them in the book drop, and sorts them based on where they need to go next. It's pretty cool to watch, and theirs is a little fancier than ours.
Damson wanted to ride on the conveyor belt, but that would have been extremely dangerous for him, so we had to watch from the side.
