This collection cotains correspondence, memoranda, contracts, programs, and other documentation about the lectureship, speakers and the content of the lectures. The collection also includes audio or video recordings of selected lectures.

Update 2017: There were 21 books in the collection that were published based on lectures given between 1953 and 1979. These books were removed during reprocessing of the collection in 2016 and given to cataloging for incorporation into the general collection.
