The John Ptak Computer Science Book Collection contains pamphlets, reports, journal articles, correspondence, software and hardware documentation, and other written material as well as more than 500 monographs and serials which are individually cataloged. The individually cataloged items are identified in the NC State University Libraries catalog as part of the John Ptak Computer Science Book Collection; they are not included in this description. The collection dates range from 1891 to 1987, but the bullk of the material is from 1940-1965. Notable authors and organizations represented include Carlo Arcelli, the Association for Computing Machines (ACM), Yehoshua Bar-Hillel, Robert J. Baron, Gordon Becker, Harry Blum, Curtiss-Wright Corporation, Walter M. Elsasser, George E. Forsythe, General Electric, J. K. Hawkins, Hewlett-Packard, Alston S. Householder, International Business Machines (IBM), William Karush, Felix Klein, Clifford J. Maloney, Jacob Marschak, Franco Modigliani, Frederick Mosteller, Ulric Neisser, W. V. Parker, Hans Reissner, Remington Rand, Inc., and Heinz Von Foerster. Topics covered include aeronautics, artificial intelligence, biology, biometrics, communications, computer science, electrical engineering, immunology, information retrieval, linguistics, logic, machine translation, mathematics, statistics, and technocracy. The majority of the material is written in English, though German, French, and Russian are also represented. John Ptak was the proprietor of J. F. Ptak Books, Maps, and Prints in Georgetown, Washington, D.C. The store specialized in used, rare, and antiquarian manuscripts, reprints, journals, maps, and prints in mathematics and the sciences.

The Llewellyn Hilleth Thomas Papers include research and lecture notes, class notes, personal papers, research papers (published and unpublished), some correspondence, documentation of consulting work, drafts of supervised student theses and dissertations, course outlines, examinations, memoranda, laboratory notes, symposiums, and miscellaneous papers. The bulk of this collection documents Thomas' academic teaching career, consisting of holograph and typed notes, most undated, on research for Thomas' physics lectures at Columbia University, Ohio State University, and North Carolina State University; also his student notes (2 boxes), taken at Cambridge University (England) physics lectures, 1921-1925, given by Bromwich, Eddington, Fowler, Littlewood, Pollard, and Ramsay, among others; published work (research published in journals), 1929-1982 (1 box); consulting for IBM and Timken Steel and Tube Company; symposiums, 1980-1985 (3 folders); personal papers (1 folder): professional diplomas and certificates as well as Lewis/Thomas family genealogy; and biographical information (1 folder). Topics: atomic physics, computer capacity, difference equations, electrodynamics, electron scattering, electronic structure of atoms and molecules, Fourier analysis, general dynamics, group theory, hydrodynamics, mathematics, physics, plasma (physics) quantum electrodynamics, quantum theory, quantum mechanics, relativity field theory, statistical mechanics, theoretical phy sics, among others. Correspondents: G. Bessis, Biedenharn, Dahl, Eichelberger, Grosch, Andrew Kollchoubey, Rolf Landauer, Lief, Robert Newton, among others. Llewellyn Hilleth Thomas (1903-1992). Physicist (atomic physics, nuclear, atomic and molecular structure, astrophysics). On the physics faculty at Ohio State University (1929-1943, 1945-1946); physicist and ballistician, Ballistic Research Laboratory, Aberdeen Proving Ground, MD (1943-1945); on the physics faculty at Columbia University from 1950, member of senior staff of Watson Scientific Computing Laboratory established by IBM at Columbia; professor at North Carolina State University from 1968. Thomas is best remembered for his work on atomic physics, particularly the development of the statistical model of the atom; concurrently developed by Enrico Fermi the model is known as the Thomas-Fermi model.
