The records contained in this collection document the activities of the Milk Consumers Association Incorporated, of DeKalb, Illinois. The materials reflect on Association business from 1922 through its 1966 dissolution, with the bulk of the materials covering the years 1950-1966.

Types of records include minutes (1950-1965), correspondence, bills, payroll records, I.R.S. materials, banking records, monthly balance sheets, hauling routes, stock inventories, stock certificates, and final dissolution shares. Additionally, there are share purchase books that record sales for most of the years between 1922 and 1952.

Although the minutes (1950-1965) provide an excellent source of information concerning the growth and development of the Association and there are records of share sales throughout the years 1920-1950, this collection lacks records which would closely scrutinize the business in its formative and middle years, 1917-1949
