This series consists of documentation concerning significant institutional settings of May's professional life and is organized into five sections: Biographical, Professional Organizations and Institutions, Teaching Materials, Union Theological Seminary, and Yale University. Each section is organized alphabetically. The first section, Biographical, includes curriculum vitae anda tribute to May by his nephew, William W. May. The tribute is a valuable summary of May's long professional career. The I second section documents affiliations with institutions and organizations, other than Yale University, which May maintained. The documents in this section are mostly routine correspondence. The Teaching Materials section contains lecture notes, course outlines, and assignments and exams for psychology courses taught by May. They are organized into two subsections: numbered and unnumbered courses. Many ofthese courses were taught by May in the Department of Psychology at Yale University. The Union Theological Seminary section primarily contains writings by May during his years ofstudying and teaching there. The Yale University section documents work at the university. The two "Department of Psychology" folders consist ofcorrespondence and minutes offaculty meetings. Most ofthese materials are not directly related to May, but they offer information about the department at mid-century. The Institute of Human Relations (IHR) materials are interesting but limited in quantity. An abstract ofsessions ofthe "Monday Night Group," IHR staff seminars held in the 1930s, details the broad intellectual concerns ofthe Institute. May's "Toward a Science of Human Behavior: A Survey of the Work of the Institute ofHuman Relations Through Two Decades, 1929-1949," offers an examination ofthe Institute, its stated goals, and its internal structure.
