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to science and society is chronicled through Survey collections (1845-present), which include published and unpublished materials available in the Connecticut Geological Survey Library Archives, and Specimen Collections.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.
