Realistisk Ordnet Avdeling (ROA) is an archive created by Rentekammeret (”Chamber of Interest”). Rentekammeret was the equivalent of the Ministry of Finance, and had a large area of responsibility.

The material in Realistisk ordnet avdeling is divided into 43 topic categories. The categorization is partly a result of Rentekammeret grouping documents pertaining to a specific case together, and partly due to  subsequent categorization of the material. The material in Realistisk ordnet avdeling makes up approximately 105 shelf meters. For more information, please see Arkivportalen.

Some of the topic categories contain oft-used material, and certain series have thus been scanned and published in the Digital Archives.
