Created and maintained by the US Federal Government, records of first transfer of public domain lands are available in multiple locations, including the National Archives and Record Administration (NARA), Bureau of Land Management (BLM), and a number of State Land Offices. Land records related to subsequent transfers of such land between parties other than the Federal Government are found at the local level, usually county.
The types of land records created by the Federal Government include survey plats and field notes, tract books with records of each land transfer, land-entry case files with supporting documents for each land claim, and copies of the original land patents.
Survey Notes & Field Plats
Dating back to the 18th century, government surveys were begun in Ohio and progressed westward as more territory was opened for settlement. Once the public domain was surveyed, the government could begin to transfer title of land parcels to private citizens, companies, and local governments. Survey plats are drawings of boundaries, prepared by draftsmen, based on data in the sketches and field notes. Survey field notes are records that describe the survey performed and are completed by the surveyor. The field notes may contain descriptions of land formations, climate, soil, plant and animal life.How to Obtain Copies of Survey Plats and Field Notes
Land Entry Case Files
Before the homesteaders, soldiers, and other entrymen received their patents, some government paperwork had to be done. Those purchasing land from the United States had to be given receipts for payments, while those obtaining land through military bounty land warrants, preemption entries, or the Homestead Act of 1862, had to file applications, give proof about military service, residence on and improvements to the land, or proof of citizenship. The paperwork generated by those bureaucratic activities, compiled into land entry case files, is held by the National Archives and Records Administration.How to Obtain Copies of Land Entry Files
