Duluth (Minn.) Library Technician Dan Buckanaga was emptying the return bin at the Duluth Public Library last week when he spotted an oddity. “I thought it was a book on disc,” he told the West Central Tribune. It was a standard 8mm movie on a reel, a media format created in the 1930s. It came with a sticky note: “Sorry, checked this out when I was 14 and we moved. It is 40 years overdue but better late than never.”
