The catalog description is different than what was originally detailed in PI 168. Above is the PI 168 description. Here is the newer catalog description:
Reports of Site Locations, 1837-1950
The forms of this series list the official name of the post office (with local name or name changes); section, township, range, and meridian in which the post office was located; terminals of the nearest postal route; mileage to adjacent post offices, rivers, and creeks; and the number of feet or rods to the nearest railroad tracks, railroad depot, or highway. A diagram or map of the location of the post office is normally on the back of the form.
These reports do not show the exact locations of post offices (except for some in the 1940s, which give street addresses), nor do they include information about the buildings in which post offices were housed or from which they operated (such as a general store).
This series was maintained by a clerk in the Office of the Postmaster General until December 1, 1905, when it was transferred to the Division of Topography which maintained the series until it was transferred to the newly created Bureau of Facilities in 1949.
