Historical Biennial Reports
1903 - 1971
The Connecticut Geological Survey has a collection of 34 out-of-print Biennial Reports of the Commissioners of the State Geological and Natural History Survey to the Governor and State Legislature of Connecticut. These historic reports chronicle the legacy and evolution of the State Geological and Natural History Survey of Connecticut from its inception in 1903 until it became an entity of the state environmental agency in 1971. These reports, ranging from 11 to 40 pages, are valuable to science historians, academic scholars, geoscience professionals, and public policy experts.
Content of the reports includes a description of Survey work during the period of the report, relevant lists of publications and water supply papers, publications in press, investigations in progress, cooperation with the United States Geological Survey and academic institutions, financial ledgers associated with contract scientists, appropriations, plans for future work, and legislation. There are separate sections within the geology program area for mapping, mineral resources, supported professors and graduate students. Within the natural history program area there are separate sections which variably include botany, entomology, ecology, and zoology.
