Through the links below, find federal land records from across the country, to include historical documents to current interactive mapping tools.

General Land Office Records 

The BLM General Land Office Records website provides online access to federal land conveyance records for the Public Land States, which are states that were created out of the public domain.  The website offers access to images of more than five million federal land title records issued since 1820. The site also has images related to survey plats and field notes dating back to 1810. Check out the GLO Records website.

The GLO Records also includes Master Title Plats (MTP), a mapping of current land status for a specified township. Other plats can be included in the MTP plat group. For example, the oil and gas and the leasable minerals plats add a graphic depiction of the current mineral lease status to the basic MTP depiction of land status. Click here for the MTP link in GLO.

Note that while the collection is extensive, this site does not contain every federal title record issued. For additional records, contact your state or local office.

Alaska Spatial Data Management System 

The Alaska Spatial Data Management System or SDMS is a one-stop tool to view, research, print and download information such as surveyed land parcels, land status, mining claims, and MTP. Click here to view the SDMS.


LR2000 provides reports on non-Alaska BLM land and mineral use authorizations for oil, gas, and geothermal leasing, rights-of-ways, coal and other mineral development, land and mineral title, withdrawals, classifications, and more on federal lands or on federal mineral estate. This is a text-based system (no online maps). Click here to review LR2000.

Mineral & Land Records System

The Mineral & Land Records System (MLRS) is a new online platform being implemented by the BLM to deliver state-of-the-art mineral and land records transactions, tracking, mapping, and more for BLM customers and staff. MLRS will combine many of BLM's current systems (i.e., LR2000, ALIS, and land status records including Master Title Plats) and manual documentation processes to create a more intuitive and efficient way to manage resources and cases across a range of BLM activities. MLRS is being implemented in phases; currently you can use the system for mining claim related filings and information. Click here for more information on MLRS.
