In the summer of 1972, the Michigan Technological University Archives and Copper Country Historical Collections became a Regional Depository for state, county and municipal documents. Working through the Michigan State Archives, governmental agencies may place certain noncurrent records on deposit in the Archives for use by residents, genealogists and historical researchers. The region embraces six counties in Michigan's western Upper Peninsula: Iron and Gogebic counties and the four Copper Country counties of Houghton, Keweenaw, Baraga and Ontonagan. Governmental records currently on deposit are predominantly from Houghton and Keweenaw counties and include survey and tax records, voting rolls, Circuit Court documents (including divorce decrees), jail records and records of district school boards. __In 1975 a grant was submitted to the National Endowment for the Humanities by the Michigan History Division to inventory county and municipal records in three regional depositories: Burton Historical Collections at the Detroit Public Library; Clarke Historical Libraries at Central Michigan University; Archives and Copper Country Historical Collections at Michigan Technological University; and Western Michigan University. Each of the institutions would conduct on site supervision with students hired to conduct the inventories. The result would be an appraisal of local records analyzing general retention and disposal schedules and would indicate which records could be preserved or discarded. Regional depositories would then accession or microfilm records selected for preservation.
