Maps

Revised January 2003

General Comments

Maps are collected to provide information in the form of graphic representations of the surface of the earth and extraterrestrial worlds. The collection includes atlases, maps, charts, and map drawings.

The collection contains 7.5 minute Topographic Quadrangles of the state of Wyoming. The Library is a government depository, and therefore collects these maps published by the United States Geological Survey.

The Map Collection holds numerous state, national, thematic, and historical atlases. Most of the atlases in the collection do not circulate due to the expense of these items.

Development Plan

The selection of maps, for the most part, will fall under the same general collection development policies which govern the Dewey number they represent.

Maps of the local area and region are in much higher demand than those of other states and regions. The Library collects all of the 7.5 minute Topographic Quadrangles for the state of Wyoming, and will continue to collect the 7.5 minute Topographic Quadrangles of the areas bordering northeastern Wyoming. Other popular areas may be considered for inclusion in the collection.

The Library collects maps in atlas format and purchases those more affordable items for circulation. The Library will also continue to acquire the majority of its holdings through the United States Geological Survey. The library is able to print these topographic quadrangles for patrons.

Influencing Factors

Purchases and buying patterns are determined in large part by:

  • items offered for selection by the Government Printing Office.
  • staffing level of government documents position.
  • electronic/Internet sources availability.
  • new works.
  • budget constraints.
  • patron requests.
  • present and potential relevance to the community.
  • shelf space.

Retention/Weeding

  • The quadrangle maps have a regulated five-year revision cycle. However, when necessary during that cycle, "reprints with changes" are purchased or printed.
  • Maps and map items are weeded using the guidelines which govern the Dewey number these items represent. For example, a map item of the planet Mars will be weeded when newer maps update the present holdings.
