Wisconsin Folklife Center documentary materials became Wisconsin Folk Museum collections after the museum opened in 1986. Ruth Forrester (formerly Fahnestock) catalogued and numbered the majority of the German-American project's documentary components in 1990-1992. This numbering system remains on the materials that were transferred from the Wisconsin Folk Museum to Mills Music Library, the Wisconsin Historical Society, and University of Wisconsin-Madison Folklore Program upon closure of the museum in 1996.
