‘A Working Partnership: Acquisitions Made With the Assistance of the W.E.B. Du Bois Institute’ will open Sept. 3 in the Amy Lowell Room, Houghton Library. Over the past 10 years, Houghton Library has worked closely with the Du Bois Institute to acquire materials to support research in African and African-American history and literature. The exhibition includes a sampling of materials acquired, including letters by W.E.B. and Shirley Graham Du Bois; material from the papers of Chinua Achebe, Albert Murray, and Nobel laureate Wole Soyinka; and rare printed materials.
