The Linguistic Atlas of the Upper Midwest includes a small amount of administrative material detailing the process of gathering field records. The bulk of the collection is comprised of completed questionnaires bound in volumes, with listings of individuals included in the volume and basic statistical information about each. Questionnaires include information such as name, county of residence, length of time the individual lived in the county, amount of schooling, and whether the individual knew a foreign language, in addition to information about language usage for common items and situations.
