CONNECTICUT GEOLOGICAL SURVEY COLLECTIONS

The State Geological and Natural History Survey of Connecticut has a long history of service to the citizens of Connecticut, beginning in 1903, the year of its formation by the State Legislature. The Connecticut Survey contribution to science and society is chronicled through Survey collections (1845-present), which include published and unpublished materials available in the Connecticut Geological Survey Library,  Archives, and Specimen Collections. Continuing data preservation efforts improve the security of these materials and increase online accessibility. 


PUBLICATIONS
Many publications are listed in a traditional catalog; others include geologic applications, maps, and digital data.  Published materials are available, at the Connecticut State Library, or for purchase at the DEEP Store.  Geologic applications and digital data are available as free downloads. Out-of-Print materials  may be accessible by contacting the Connecticut Geological Survey.
