The William Stephen Moss Collection includes information on the conditions of Northern prisons during the American Civil War and Moss's personal life. Letters from Washington, D.C.; Point Lookout, Maryland; and Elmira, New York stem from Moss's capture at the Germana Ford in 1863. One letter predates Moss's capture. Specifically, in these letters Moss discusses his desire for a prisoner exchange, the disinterest of authorities in prisoners, endemic sickness, and the tradability of tobacco for stamps. Many original POW covers (envelopes) are included and are marked with signed approval and original postage. Also in the collection is a biography written by Moss's son, William D. Moss, and a hand-tinted photograph of an elderly Moss with a hunting dog lounging near a tree.
