Two typescript copies of a Ph.D. dissertation by Hollis which he wrote as a candidate for a Ph.D. in political science at Columbia University. The early version (1955, 596 p.) is incomplete, including most of the first eight chapters of a projected eleven-chapter work. The later version (1957, 695 p.), which comprises an edited text of the original thesis and the final three chapters, appears to be Hollis' final draft. The collection also contains a microfilm of the second version.
