The Collectors' Institute was a private association of collectors of library materials, including books, manuscripts, documents, and maps, cosponsored by the Texas State Historical Association and the Harry Ransom Humanities Research Centerqqv of the University of Texas at Austin. It was organized on November 23, 1968, with more than 150 members. Between the fall of 1969 and 1980 twelve annual meetings were held, with programs of general interest in the area of publishing, authors, and collections. Speakers included Carl Hertzog, Hallie Stillwell, Lawrence Clark Powell, Archibald Hanna, J. Evetts Haley, and John Graves. In addition to annual meetings, workshops were held each spring. The workshop programs focused on questions of interest to collectors, such as identity, preservation, repair, and maintenance of printed and manuscript material.
Through 1973 transcripts of the meetings were published and distributed to the membership. Jenkins Garrett was president of the Collectors' Institute from 1968 through 1980. From its organization in 1968 through the fall of 1970 Kenneth Ragsdale, a fulltime staff member of the Texas State Historical Association, served as voluntary secretary and coordinator of the institute. In 1974 John Payne, a fulltime employee of Humanities Research Center, volunteered to take over these responsibilities. He served through the fall meeting of 1980. The organization was discontinued after that meeting.
