Maps Reference Area in Paley Library
The Map Reference Area - located at the east end of the library's first floor.
- Current issues of most atlases are available in the general reference area.
- Most of the flat maps are located in the Map Reference Area. These are primarily 7.5 minute topographic maps from the U. S. Geological Survey. Each state is divided into many quadrangle maps, each of which has a name located in the lower right corner of the map, and which are filled in the appropriate state drawer alphabetically by map name. To find the quandrangle map with the feature you are looking for, use the Geographic Names Information System (GNIS) online, or use the print OMNI Gazetteer of the United States of America to find the name of the map you need. You do not need to know which state contains the feature you are looking for if you use the GNIS online, but you do need this information to use the OMNI Gazetteer. For example: a student needs to find the map which contains the Craters of the Moon National Monument. If using GNIS online, type in the name of the feature in the box for FEATURE NAME, and other other information, but the feature name is usually sufficient; if using the OMNI Gazetteer, you must also know the state where the feature is located because you must choose a state volume. If you search GNIS online, using only the feature name Craters of the Moon, you are given four choices, all of which are located in Idaho, and three of which are located on the map with the name INFERNO CONE:
