The Clemson files from 1932-1984 contain a large amount of athletic and IPTAY information, IPTAY Board of Director's minutes, IPTAY membership campaign literature, applications for athletic season and ACC tournament tickets, mailings and statistics from the athletic department, evidence of much work on IPTAY's constitution and subsequent revisions. The files also include some correspondence with individuals connected with Clemson's athletic program such as Coach and Athletic Director Frank Howard; Athletic Director H. C. "Bill" McLellan; Eugene P. Willimon, George Bennett, and Joe Turner, Executive Directors of IPTAY; Frank J. Jervey, Vice President for Development and early organizer, with Dr. Fike, of IPTAY; Rupert H. Fike, M. D., founder and historian of IPTAY; Robert C. Edwards, president of IPTAY and later President of Clemson University; coaches of all sports; Charles Bussey, IPTAY director and president; representatives of local county IPTAY organizations; and fellow IPTAY board members. These files contain information about early attempts to end the Big Thursday football game between The University of South Carolina and Clemson.

Lemon was a major contributor to writing and revising the IPTAY constitution. He, with Dr. Rupert Fike, gathered historical data and funds for a history of football at Clemson. Dr. Fike prepared a rough draft of a history before he died. The Library has some of the research materials in Mss 34 as well as in this collection, such as a handwritten IPTAY constitution and copies of the membership ritual; the retirement of Frank Howard; the enlarging and naming of the stadium; a proposal for the Sport and Society Conference; investment and expenditures of IPTAY surplus funds; Memorial Stadium and the executive box suites and Lemon's reasons for not wanting one, though eligible; and the NCAA and ACC investigations of Clemson's athletic program.

Over the years, Lemon demonstrated an interest in the total development of the University. Evidence of his wide support through his service to the Alumni Association, the Board of Visitors, and as a vital member of the Clemson University Foundation is found in this collection. There is some correspondence with such correspondents as Liberal Arts Dean Morris Cox, Dr. M. A. Owings, Chairman of the English Department, Melvin Barnette, Vice President for Business and Finance, and others associated with the Clemson University Foundation and the Loyalty Fund. Accounts of the appointment of two outstanding scholar-teachers in the English Department before the endowed chair's permanent professor, Roger Rollin, was hired are also found in this collection.
