Navy and Marine Directories
These directories are registers of officers, and sometimes cadets and midshipmen, in the Navy, Marine Corps, and US Naval Reserve for periods including 1776-1887, WW I and WW II. As far as we know, they are not available online elsewhere and are a gold mine of information for genealogical researchers and military historians.
Please note, due to the tight binding of some volumes, small amounts of text near the middle of some books may not be as readable as other parts of the book. Every effort was made to include the full page in the resulting image without damaging the spine or other parts of the book.
