The University Cellar was a student-run bookstore at the University of Michigan which was established 1970 and which ceased operation in 1987. The Bentley Historical Library holdings include minutes and memoranda of board of directors, financial records, labor negotiation files, and other subject files; and photographs.
The bookstore was in the basement of the Michigan Union until 1982, when it moved to the former Handicraft Furniture building on East Liberty Street.
Workers at the U Cellar were represented starting in 1979 by Local 660 of the Industrial Workers of the World; at the time, the union local was the largest of the Wobblies, representing 10% of total union membership worldwide.
