      <Desc>The Dunn County Historical Society brings together people interested in the history of Dunn County for the purpose of collecting and preserving historical records and material pertaining to the history of Dunn County and to cooperate with others around the state for this purpose. A museum and other various facilities showcase the historical collections. These artifacts and historical records and documents are available for the public to view and to use for research. Approximately 500 people visited these facilities for these purposes or to attend events held at these facilities. An Oral History project records audio histories as told by local residents and also provides transcriptions of these. These are available to the families that provided the information and also to the public for research. A genealogy research group meets at the Museum approximately 9 -10 times per year with a volunteer leader/instructor.</Desc>

        <ExplanationTxt>The Dunn County Historical Society maintains Museum facilities for historical and educational purposes which are available to the public for viewing of historical artifacts and photographs and to research and view family and community history and genealogy. Facilities include a main Museum building, a building to display machinery and vehicles, a former bank building and a former country school house. Educational opportunities for tours including students from local schools are available year round. The DCHS also provides for the ability to collect Oral Histories and to make them available to the public in audio and transcribed formats. The DCHS has published two collections of historical information of families who homesteaded and lived in Dunn County and a new edition to collect more information and update family information from the previous volumns is currently being produced and will be available in 2026. Genealogy classes which include helpful information for doing reseach and creating and preserving family ancestries and histories are provided for the public. These family genealogies will also be a part of the DCHS's collections for research.</ExplanationTxt>
