MARYVILLE, TN (AP) - An East Tennessee post office has begun throwing away books sent out through Dolly Parton's Imagination Library program that are returned due to wrong addresses.

Members of the Maryville Kiwanis Foundation used to be able to pick up the returned books free of charge, but recently officials with the Postal Service said they can't allow that anymore. 

David Walton, spokesman for the Tennessee District of the U.S. Postal Service, said the practice is expensive and can't be continued, especially when the agency is facing financial woes of its own. The Postal Service lost $15.9 billion last year and has announced plans to stop Saturday mail delivery in August. 

Kiwanis member Herb Meyer says it seems "a shame" to discard about 100 books a month.
