The Compiled Data series of the Norby Collection consists of reference data compiled by George and Evelyn Norby and recorded into various databases. The material documents the city of Brookings with limited coverage of Brookings County and the state of South Dakota. The series includes compiled information on city and county officials, appointed officials, elections, mayors and commissioners, attorneys, governors, and public offices such as police, fire, sheriff, and post office. It also contains extensive data on streets, avenues, homes, apartments, mobile homes, building permits, businesses, churches, health care providers, newspapers, and civic services. Additional components include birth, death, and marriage data, obituary indexes, cemetery and church burial records, census information, city charters, historical summaries, business chronologies, National Register documentation, and records related to South Dakota State University buildings. Telephone books spanning the early twentieth century through the mid twentieth century are also included. Materials date primarily from 1871 to 2003 and are organized by subject across multiple boxes.

The Compiled Data series provides a reference resource documenting the administrative, geographic, social, and economic development of Brookings over more than a century. By aggregating information drawn from newspapers and other local sources, the series supports research in local history, genealogy, urban development, governance, and community studies. The data reflects sustained private documentation efforts that preserve contextual information not consistently available in official municipal records.
