This series was maintained by Malawista's successive secretaries who created files for talks away from Yale and for professional meetings. Sometimes folders were created for events Malawista probably didn't attend. Additional material on talks and meetings was found loose in Malawista's papers and added by the archivist to "T/T." Folders may contain correspondence, programs, announcements, abstracts of papers that Malawista and his colleagues presented, texts of talks, and occasional photographs.
