The Prince George's County Memorial Library System said staff at the Laurel Branch Library were shocked to discover a Wish You Were Here CD that had been due back 35 years earlier. Advertisement The CD was placed into the library's return box, and it had been gone so long that it wasn't in the library's computer system, so the patron who returned it remains a mystery. The library said the patron would not be charged anyway, as the facility is now fine free.
