The Western Michigan University Archives and Regional History Collections consists of historical University, regional, and local governmental records. The holdings total over 28,000 cubic feet, making the WMU Archives the largest facility of its type in southwestern Michigan and one of the largest in the state. In addition to the manuscript collections, the unit has oral histories, census records, a research collection of books, magazines, and newspapers, and several large photographic collections.

The Archives and Regional History Collections are now located in the new Charles C. and Lynn L. Zhang Legacy Collections Center. The new facility opened in October 2013.
