On one side of the machine, which is two-thirds the length of a football field and encircled by a conveyor belt, staff members place each book face-down on a separate panel of the belt. The book passes under a laser scanner, which reads the bar code on the back cover, and the sorter communicates with the library’s central computer system to determine where the book should be headed. Then, as the conveyor belt moves along, it drops the book into one of 132 bins, each associated with a branch library. It’s sort of like a baggage carousel that knows which bag is yours and deposits it at your feet.
My inner geek is giddy with excitement.
