The Database series is composed of material compiled by George Norby documenting topics related to Brookings, South Dakota. The material includes information on local businesses, historic homes, churches, city and county government, and South Dakota State University.

As noted by George Norby, the information contained in these compiled databases was gathered from multiple sources and reflects the most accurate data available to him at the time of compilation. Sources used include the Brookings County Press, the Brookings Register, the Brookings County Sentinel, Brookings telephone and business directories, Brookings city publications, Brookings County election returns, Brookings County Commission minutes, and records from the Brookings County Register of Deeds office.

Although the compiled data is extensive, researchers are encouraged to verify information using more than one source when conducting research.
