Research maps by subject
Maps are powerful tools for exploring spatial relationships across a wide range of research topics, from human settlement patterns to the distribution of natural resources. This section highlights maps useful for subject-specific research, including geology and mineral exploration, historical and military studies, public lands (BLM, Forest Service, National Parks), navigation, and genealogy.
Geologic and Mineral Research
Science and engineering fields often rely on maps that detail an area’s geology, mineral resources, hydrology, and related features, making them essential tools for research and exploration.
- NBMG Physical Map Collections: C103 – C105, F68 – F72
- USGS Physical Map Collections: C1 – C23, F1 – F54
- M. Keck Earth Science & Mining Research Repository
- Nevada Bureau of Mines and Geology
- National Geologic Map Database
Historic Research
Maps are valuable tools for historical research, revealing how cities have evolved, political boundaries shifted, and place names changed over time.
- Historic Topographic Maps of Nevada: C64 – C69, C101
- Historic Topographic Maps of California: D34-35
- Historical Topo Map Explorer
- Historic Atlas of the United States
Forestry, BLM, National Parks Research
Maps of U.S. National Forests, Bureau of Land Management (BLM) lands, and National Parks offer valuable information on land use, recreational areas, and regulations for activities such as camping, hunting, fishing, and motor vehicle access.
- Forest Service Map Collection: G1 – G20
- BLM 1:100,000 Map Collection: C24 – C42
- BLM Recreation Maps: throughout US State General Drawers
- National Parks Map Collection: G33 – G35
- United States Forest Service Maps
- BLM Maps
- National Park Service Map Finder
Navigation
Navigational maps support air, sea, and land travel by showing routes, hazards, and features such as sea depth, currents, and terrain. These include aeronautical and nautical charts, as well as highway maps, road atlases, and other land navigation resources.
- NDOT Map Collections: C97 – C100
- NOAA Nautical Charts Collection: B51 – B95
- PAIGH Map Collection: B47

- NOAA Nautical Chart Locator
Military History
Maps from the Army Map Service (AMS), Defense Mapping Agency (DMA), and British GSGS offer detailed views of global terrain, conflict zones, and wartime infrastructure. These are key resources for studying historical military strategy, operations, and shifting borders in the 20th century.
- AMS/ DMA Topographic Map Collections: A51 – A69, A77 – A95, B1 – B43
- GSGS Topographic Map Collection: A70 – A76
- AMS & GSGS Map Indexes (UC Berkeley Library)
- The Army Map Service Map Collection (CSUN University Library)
Genealogy Research
Maps, atlases, and gazetteers can help identify old place names, historic property boundaries, and even the locations of buildings or neighborhoods that no longer exist. These resources provide valuable geographic context that can help connect information across generations. While the Mary B. Ansari Map Library does not hold physical Sanborn or General Land Office (GLO) maps, it has a digital map collection and a collection of atlases and gazetteers that support genealogical research.
- Nevada Sanborn Maps, 1885-1923 (University Libraries Digital Map Collection)
- General (State) Land Office Maps (University Libraries Digital Map Collection)
- Sanborn Maps Collection (Library of Congress, Digital Collections)
- General Land Office (GLO) Records Site (Bureau of Land Management, BLM)
