The National Catholic Welfare Council (NCWC), consisting of the American bishops and its working secretariat, was established in 1919, and eventually evolved into the U.S. Conference of Catholic Bishops (USCCB), as it is known today. The Archives houses the papers of the USCCB from its inception to the present day. Among the many records deposited from the organization to the Archives are the glass lantern slides that were donated in 1996. Glass lantern slides were a popular format used for both educational and entertainment purposes throughout the beginning of the twentieth century. More than 100 lantern slides are digitized here, focusing largely on USCCB activities involving service in the Second World War.
