Register of the Commissioned, Warrant, and Volunteer Officers of the Navy of the United States: Including Officers of the Marine Corps and Others, to January 1

The Register of the Commissioned, Warrant, and Volunteer Officers of the Navy of the United States was an essential administrative publication issued annually or biennially by the United States Department of the Navy. These volumes served as the official personnel directory for the naval service, documenting the rank, assignment, and status of every commissioned officer, warrant officer, and member of the Marine Corps. Their primary purpose was to provide a transparent, centralized record for government accountability and organizational management during a period of significant growth for the American maritime forces.

The design of these volumes prioritized utility and clarity, adhering to the standardized government printing styles typical of the 19th and early 20th centuries. Produced by the Government Printing Office, they were compiled by the Bureau of Navigation to ensure accuracy in seniority lists and station assignments. Because they functioned as internal reference tools for the military establishment, they were not intended for public commercial consumption, though they remain vital primary sources for historians and genealogists researching American naval evolution and individual military careers.
