|U.S. Congressional Serial Set Maps
The more than 50,000 maps in the U.S. Congressional Serial Set range from the great atlases to small individual maps clarifying very specific land questions, to the great triangulation surveys, to the repetitive but for the meteorologist important weekly weather maps, to the maps that made history as well as the maps of past history and of course to the purely serendipitous, or so it would seem, maps found in the Serial Set.
Since some maps lack titles and many are not listed in the introductory matter of the Reports and Documents, which they accompany, they have been difficult to research - especially since all the subjects depicted on a map may not have merited indexing in the index coverage of the whole Report or Document. Readex has created this additional search module to focus searches on maps themselves - the geographic areas they depict, the subjects they represent, their titles, and the names associated with the maps either as cartographers, explorers, or in some other capacity.
