The Credo online repository contains over 40,000 items held by the University of Massachusetts Amherst Libraries' Department of Special Collections and University Archives. During the launch of Credo in June 2011, the organizers digitized and released the complete papers of noted African American intellectual and activist W.E.B. Du Bois. This project was made possible with support from the Verizon Foundation and the National Endowment for the Humanities. Visitors can browse Du Bois' papers here and also look over the Halpern photograph collection. These photographs were taken by noted anthropologist Joel M. Halpern and they document his extensive visits to the Arctic in the 1950s. Visitors looking for a bit more orientation to the entire Credo repository should look over the "How To Use Credo" guide.
