FEDERAL DEPOSITORY PROGRAM

As a federal depository library, Portland State maintains a complete collection of current maps produced by the U. S. Geological Survey, the Defense Mapping Agency, and the National Oceanic and Atmospheric Administration. Also lesser collections produced by, or for the U.S. Bureau of Land Management, U. S. Forest Service, Central Intelligence Agency, etc.

COLLECTION DEVELOPMENT POLICY

The federal depository collection is supplemented by gifts and purchases. Geographical priorities for acquisition/collection development are:

1. Portland, Oregon and adjacent counties (All scales and subjects, including pre-1900 maps and facsimiles, including atlases, gazetteers, and ephemeral travel materials)
2. Oregon (All scales and subjects, including atlases, gazetteers, and ephemeral travel materials, pre-1900 maps and facsimiles.)
3. Pacific Northwest, including Idaho and Washington (All subjects, selected scales, including atlases, gazetteers, and ephemeral travel materials)
4. United States (Thematic maps of the United States as a whole; sectional maps; atlases and gazetteers; regional and state-wide maps, with priority given to the western states, and areas of special interest.)
5. Canada, Mexico (Thematic maps as a whole. Atlases and gazetteers; and regional maps of scale 1:250,000. Maps of province-wide scope. Larger scales as budget allows.)
6. World, with emphasis on Pacific Rim countries. (Thematic maps, atlases and gazetteers of the world and of major ocean basins. Also continents and individual countries as a whole, including regions of special significance.

Many of the maps are imperfectly cataloged--or not at all. Reliance must be placed on various map catalogs, indexes, and guides. An on-line tour of the collection has been created; as well as a detailed guide to finding maps, and a special guide to the maps and atlases of Oregon.
