TheGeneral Land Office (GLO) was anindependent agency of the United States government responsible forpublic domain lands in the United States. It was created in 1812 to take over functions previously conducted by theUnited States Department of the Treasury. Starting with the enactment of theLand Ordinance of 1785, which created thePublic Land Survey System, the Treasury Department had already overseen the survey of theNorthwest Territory, including what is now the state of Ohio.[1]
Placed under theDepartment of the Interior when that department was formed in 1849, it was merged with theUnited States Grazing Service (established in 1934) to become theBureau of Land Management on July 16, 1946.

The GLO oversaw thesurveying,platting, and sale of the public lands in theWestern United States and administered theHomestead Act[2] and thePreemption Act in disposal of public lands. The frantic pace of public land sales in the 19th century American West led to theidiomatic expression "land-office business", meaning a thriving or high-volume trade.
For most of the active period of public land settlement, district land offices were the basic operating units that conducted the business of transferring title. All transactions relative to the disposal of public land within a declared land district were handled through its land office by officials designated asregisters, who recorded land applications, andreceivers, who accepted payments for land and issued receipts. The position of receiver was abolished, July 1, 1925, and the functions devolved upon the register, whose title was changed to "manager" in 1946. The first of 362 district land offices was opened atSteubenville, Ohio, on July 2, 1800; the last atNewcastle, Wyoming, on March 1, 1920. The peak year for land offices was 1890, with 123 in operation. The subsequent closing of the public domain gradually reduced the number of land offices, until, in 1933, only 25 offices remained.[3]
The GLO was placed under theSecretary of the Interior when the Department of the Interior was formed in 1849. Reacting to public concerns about forest conservation, Congress in 1891 authorized thePresident to withdraw timber lands from disposal.Grover Cleveland then created 17 forest reserves of nearly 18,000,000 acres (73,000 km2), which were initially managed by the GLO. In 1905, Congress transferred responsibility for these reserves to the newly createdForest Service, under theDepartment of Agriculture.
Beginning in the early 20th century, the GLO shifted from a primary function of land sales to issuingleases and collectinggrazing fees for livestock raised on public lands, androyalties fromminerals off lands recently withdrawn from disposal under the Withdrawal Act of 1910, as well as other custodial duties. Thus, beginning around 1900, the GLO gained a focus for conservation of renewable public resources, as well as for their exploitation.
On July 16, 1946, the GLO was merged with theUnited States Grazing Service (established in 1934 under theTaylor Grazing Act) to become the Bureau of Land Management (BLM), an agency of the Interior Department responsible for administering the remaining 264,000,000 acres (1,070,000 km2) of public lands still in federal ownership.[4]
An early commissioner wasJohn McLean, later anAssociate Justice of the Supreme Court of the United States.
The BLM makes images of GLO records (federal land patents, survey plats and field notes, land status records, and tract books) issued between 1787 and present publicly available on its website.[5]Since 1990, the BLM's Geographic Coordinates Database (GCDB) program has endeavored to generate coordinate values for each establishedPLSS corner using the official survey records of the GLO and BLM on a township basis. The GCDB data are available for download by the public in GIS shapefile format from the GeoCommunicator Land Survey Information System website. The GCDB coordinates are also available to the public in the GCDB flat file and GCDB coverage formats via the National Operations Center website.[6]
