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.
US Geological Survey (USGS) State Maps (I 19.102/) • Excellent base maps. • Can be plain, with topography, or with shaded relief.
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.
Castle Rock Topos • 1:500,000 1980 • 1:250,000 1978 • 1:125,000 1898 • 1:125,000 1913
Castle Rock Topos • 1:100,000 1983 • 1:62,500 1945 • 1:50,000 1976
Castle Rock Topos • 1:24,000 1965 • 1:24,000 1971 • 1:24,000 1980 • 1:24,000 1994
USGS Topo Indexes (I 19.41/6-3) • Free. • Need for topos.

TPC (Tactical Pilot Chart) (D 5.354) • 1:500,000 world-wide, topographic coverage. • None have come through the FDLP in years.
Sectional Aeronautical (TD 4.79/11) • 1:500,000 USA. • Updated and distributed twice a year.
NOAA, DMA/NIMA Nautical Charts (C 55.440, TD 4.82) • USA and worldwide coverage. • Not all issued/released.
CIA (PrEx 3.10/4) • Excellent for displays or reports. • Very simple. • Some very current.
FIRM (Flood Insurance Rate Map) (HH 10.9/2) • Shows flood prone areas. • Most out-of-date. • Newer ones online.
Soil Surveys (A 57.38) • Not all of the US done—most of the mountainous regions skipped. • Soil types on top of aerial photographs.

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.
