The Hillsboro Public Library has an automated book return and sorting system. What’s cool is that the library doesn’t hide this in the basement somewhere. Instead, it’s visible through big glass windows right beside the main entrance.
When a librarian saw me taking video, she invited me in and gave me a tour. Then she “put on the duck”1Apparently, when they see kids watching through the windows, they’ll put the duck on the conveyor to make the sorting more obvious, or fun. Works for me! :-) for me so I could go back outside and take this video.
