The overdue book stories just never get old for me. The Mercury News reports on a Library book returned 78 years late by an Alabama man. He discovered a national parks volume borrowed from an Ohio library in April 1927. He says he is relieved he won't get charged for this overdue book. Library spokeswoman Carla Davis said she doesn't know of any other books that have come back so tardy, although a lot of overdue materials are still out -- some 20,000 were due to be returned on Monday alone.
