Paul Batesel, a former colleague and emeritus professor of English at Mayville State University has created an amazing site devoted to the history of institutions that have closed.
America's Lost Colleges includes separate pages for 200 institutions that can be reached from a central index of Lost Colleges by State. Batesel conducted research using yearbooks and newspapers. He also visited a quarter of the institutions. Each institutional page includes a historical sketch, photographs, sources of information, and highlights intended to capture the soul or spirit of the learning community.
