Most map librarians know about the Tiger Mapping Service, but for those of you interested in learning more, check out the U.S. Census Bureau's Mapping and Cartographic Resources.

TMS is a geographic map service which produces public domain GIF images of map data which is derived from Tiger/Line® data. The primary goal of the service is to provide a public resource for generating high-quality, detailed maps of coverage within the United States and outlying areas, using a public geographic data source.
