A vast collection of geologic reports (bedrock and surficial) including, but not limited to, bulletins and resource surveys, most with accompanying quadrangle or field maps. Publications date back to the 1950's and include a comprehensive geologic history of the mapping area. A large percentage of these publications are out of print and do not exist in any other form. Some are rare publications, which exist only in the State Geologist's archive. Most of these maps and reports were published by the Department of Resources and Economic Development (DRED) and the New Hampshire State Planning and Development Commission. Geologic information included in these publications has not be reproduced elsewhere, and is only available through the New Hampshire Geological Survey.
