Here we have an addition to Dr. Sandra L. Planisek's collection documenting the pipeline under the Mackinac Bridge. The addition includes a number of interviews on CDs. The bulk of her collection is information gathered on the Enbridge Energy line 5, which carries oil under the Straits of Mackinac.
Last we have a new collection of Don Gates, a 1944 war years graduate of Central State Teachers College (CSTC). The donation consists mostly of publications and clippings from his time at CSTC.
