Introduction

The US Navy Z Files are located in the Navy Department Library's Rare Book Room. Originally, they were in the custody of the Office of Naval Records and Library after that organization's other early record holdings were accessioned by the US National Archives and Records Administration in 1942. For many years, the Z Files were physically located at an office provided by the National Archives for the Navy's Early Records Section. In 1972, the Z Files were relocated to the Operational Archives Branch of the Naval History and Heritage Command on the Washington Navy Yard. In 2002, these records were transferred to the Navy Department Library.

These files have been accumulated over a period of many years by the Naval History and Heritage Command and its predecessor offices to provide historical information to US Navy personnel and other researchers, both official and unofficial. A large portion of the material consists of Office of Naval Records and Library and Naval History Division correspondence, forwarding the results of research in archival and published materials. Intermixed with these letters are numerous historic documents and manuscripts (both originals and copies) that were acquired from a variety of sources. Original and photocopied documents and journal articles continue to be added to these files.

The Z Files are particularly notable for biographical coverage of 19th century naval officers. However, many other aspects of early naval history are documented in the files.

Use and Reproduction Policy

Z File materials are unavailable for loan and must be consulted in the library. Photocopying of manuscripts, as well as fragile items, is generally prohibited, though the use of digital cameras by researchers to reproduce non-copyrighted materials is permitted. Permission to photocopy a few pages may be granted by the reference staff, contingent upon the physical state of items. All photocopying of materials shall be done by the reference staff, or under their close supervision. The use of personal scanners by non-library staff personnel must be approved by the reference staff on a document-by-document basis (Reference: Naval History and Heritage Command Instruction [NAVHISTCENTINST]5070.1C.).
