Correction: An earlier version of the obituary for library assistant Ruth L. Wells incorrectly identified the city in which Mrs. Wells volunteered with the Friends of the Library. It was Wheaton, Md., not Silver Spring, Md. Also, she organized the first parent-run library at the old Forestville Elementary School in Forestville, Md., not Forestville Elementary School in Great Falls, Va. Additionally, an earlier version of the obituary for postal police officer Thomas L. Briscoe incorrectly identified him in one reference as an Army colonel. He was a retired Army staff sergeant. This version has been updated
