Since 1920 the historians of the United States Marine Corps have produced several hundred works on Marine Corps history. These have ranged in length from a few pages of mimeographed material to lengthy case-bound histories sold by the Government Printing Office (GPO) through the Superintendent of Documents. This catalog is in two parts. The first lists those publications still in print and available from the Superintendent of Documents or only from the History and Museums Division. The second part of the catalog is a chronological list of all significant historical publications that were officially produced or sponsored by the History and Museums Division and its predecessors. Operational and administrative histories of the Marine Corps are listed in chronological order under the "General Histories" section of this catalog. The division is currently engaged in writing a nine-volume chronological history of Marine Corps operations in Vietnam, the first five volumes of which are listed in this catalog.
