2. National Atlas of the United States of America 1970 Every library should own.

3. National Atlas Sheets (I 19.111) Some plates from 1970 Atlas. Most new sheets available on web, but some printed. Libraries should get if they have cabinets.

4. US Geological Survey (USGS) State Maps (I 19.102/) Excellent base maps. Can be plain, with topography, or with shaded relief.

5. USGS Topos (I 19.81, I 19.110) Excellent for historical research. Some sheets up-to-date, others over 50 years old. Different scales. Complete coverage of the US. Good to own maps of your library’s city and county--$6 each.

6. Castle Rock Topos 1:500,000 1980 1:250,000 1978 1:125,000 1898 1:125,000 1913

7. Castle Rock Topos 1:100,000 1983 1:62,500 1945 1:50,000 1976

8. Castle Rock Topos 1:24,000 1965 1:24,000 1971 1:24,000 1980 1:24,000 1994

9. USGS Topo Indexes (I 19.41/6-3) Free. Need for topos.

10. USGS National Parks Maps (I 19.106) Most out-of-date. Show topography and often shaded relief.

11. National Park Service Maps (NPS) (I 29.6/, I 29.8, I 29.21, I 29.39) Black boarder. Given away at park entrances.

13. Bureau of Land Management (BLM) (I 53.7/2, I 53.11) Similar to Forest Service. Surface and Mineral Management maps immediately obsolete.

14. AMS/DMA/NIMA/NGA World coverage. Most date from WWII and immediately after. Good for finding old names of cities in Europe.

15. TPC (Tactical Pilot Chart) (D 5.354) 1:500,000 world- wide, topographic coverage. None have come through the FDLP in years.

16. Sectional Aeronautical (TD 4.79/11) 1:500,000 USA. Updated and distributed twice a year.

17. NOAA, DMA/NIMA Nautical Charts (C 55.440, TD 4.82) USA and worldwide coverage. Not all issued/released.

18. CIA (PrEx 3.10/4) Excellent for displays or reports. Very simple. Some very current.

19. FIRM (Flood Insurance Rate Map) (HH 10.9/2) Shows flood prone areas. Most out-of-date. Newer ones online.

20. Soil Surveys (A 57.38) Not all of the US done—most of the mountainous regions skipped. Soil types on top of aerial photographs.

21. USGS Thematic Maps— (I 19.85:C), (I 19.89:HA, (I 19.91:I), (I 19.87:GP), (I 19.88:GQ), (I 19.113:MF), (I 19.90:MR), (I 19.92:OC), (I 19.93:OM), (I 19.91/3:SIM) All discontinued except SIM (paper), and MF (digital). Usually show geology and usually show USA. Not all of the US mapped geologically. Some mapping of Pakistan (satellite), other planets and the moon.

22. USGS Geologic Atlas (I 19.5/) Covers only parts of the country—mostly mining areas. Most about 100 years old. Collectors’ items.

23. Open-File Reports (OFR) (I 19.76) Most have maps. Most show geology. Blueline copies—print-on- demand. Most not distributed in paper form via the FDLP. Some distributed from 1990- 2000 in microfiche. Some issued on cd-rom. Most new ones available on the web—some old ones too.

24. Census (C 56.242, C 56.242/2, C 56.242/3) Variety of themes including elections and congressional districts Census boundary maps are no longer printed in paper form.
