DEEP is excited to be getting back to our new normal consistent with the direction of Governor Lamont and as a result of the rapidly improving COVID-19 situation in Connecticut. Starting no later than June 1, all customer facing services will resume normal business operations.

LIBRARY LEGACY COLLECTIONS [1835-2020]

The Legacy Collections include a comprehensive assemblage of Connecticut Survey documents, including geologic maps and reports, historic correspondence, unpublished field manuscripts, scientific specimens, geoscience data, publication originals, and Open File documents. The State Survey Library is both an historic research library and a modern collection, in continual use by Connecticut Survey staff, students, volunteers, and external scholars. The Survey Library Legacy Collections are located at DEEP headquarters in Hartford, Connecticut.  Holdings include contributions that pre-date the establishment of the State Geological and Natural History Survey of Connecticut in 1903, with catalog entries dated from 1835 to the current year, 2020.

Published materials are accessible online, at the CT State Library, or for purchase at the DEEP Store.

Out-of-print or unpublished materials that are not available here may be accessed by contacting the Connecticut State Geologist
