Annual Reports
The Annual Report series was established in 1892 to publish both administrative reports and results of geological investigations. Reports in the series include information on the geology of Iowa's counties, summary assessments of Iowa's mineral resources (coal, gypsum, sand and gravel, etc.) and summary reports on Iowa's water resources. Annual Reports in this format were issued from 1893 to 1941 when they were discontinued. These reports were the first detailed, systematic reports on Iowa's geo

Early State Surveys
During the mid-1800s the Iowa Legislature authorized two surveys of the geological resources of the state. These were the first geological surveys of Iowa and, although they were reconnaissance studies, they established an initial framework of the state's geology and related it to that of adjacent states. This work has been superseded by subsequent geologic studies, but is useful for historical perspective. The preservation quality of volumes varies.

Report of Investigations
The Report of Investigations is a discontinued series of technical reports on specific topics of Iowa geology. These reports were the first detailed studies on certain aspects of Iowa geology, and are historically important. Some concepts and conclusions in some of the Report of Investigations series are now considered out-of-date as a result of more recent findings. Similar technical reports are now published as the Technical Information Series.
