The collection consists of research reports, booklets, published articles, lecture notes, and audiovisual materials that describe the development of the EDVAC, ENIAC, and UNIVAC computers. The materials are organized into five series by format: Manuals and pamphlets; Articles and reprints; Tributes and anniversary materials; Photographs and films; and Objects.

The Manuals and pamphlets series provides technical and instructional information about the ENIAC, UNIVAC, SWAC, and LARC computing systems. There are technical manuals, operational manuals, lecture materials, and informational booklets/pamphlets. Much of the materials are intended for educational use; the manuals date from 1946 to 1968.

The Articles and reprints series mainly covers the history of computing, the Sperry Rand Corporation, and the UNIVAC computer. The materials date from 1945 to 1968. Of particular interest is a lecture by J.W. Mauchly and "A Complete EDVAC Computing System," prepared by J. Presper Eckert in 1947. Bergin prepared Eckert's description of the EDVAC computer for re-publication in 2014, titled "What is a computer? An Answer from the Past," which appeared in the IEEE Annals of the History of Computing. The collection includes the original documents of Eckerts with hand-drawn diagrams, as well as Bergin's research notes and correspondence with editors. Additionally, there is documentation related to the CBS coverage of the Eisenhower/Stevenson election on November 4, 1952. Earlier that year, the Columbia Broadcasting System (CBS) arranged to use a UNIVAC to predict the outcome of the presidential election between General Dwight D. Eisenhower (Rep.) and Senator Adlai Stevenson (Dem.) based on statistical samples of election returns. The first computer printout, at the early time of 8:30, predicted a win for Eisenhower. This was not expected, so it was not reported. CBS correspondent Charles Collingwood came on the air later that night and confessed that UNIVAC had made that prediction, but CBS had not aired it. Documentation includes hand-printed notes for the CBS broadcast, a Westinghouse radio script, advertisements highlighting the output, a "Report to the West" typescript by Charles Collingwood, and a paper about UNIVAC's prediction written by A.F. Draper of the Remington Rand Laboratory that explains how UNIVAC employees approached the prediction and how the system processed the data. There are also follow-up materials for the 1956 election, an advertisement encouraging people to watch CBS after they cast their vote and an "insider's look" at UNIVAC to predict the 1956 election by an unknown author.

The Tributes and anniversary materials series primarily includes commemorative booklets about the history of ENIAC and innovations in computer technology. The booklets were released, marking an anniversary of a significant information technology event. Between 1943 and 1951, John W. Mauchly and J. Presper Eckert and their associates at the Moore School of Electrical Engineering at the University of Pennsylvania built six of the world's first electronic digital computers. Since then, the Moore School of Electrical Engineering is often considered the birthplace of the computer industry. There are a number of publications from the Moore School commemorating the ENIAC computer. The Association for Computing Machinery (ACM) is a professional membership group for scientific and educational computing. One of ACM's major annual events is Computing Week. In 1996, the conference celebrated the 50th anniversary of EINAC. Bergin chaired a six-session series on computer history. There is an autographed conference program and conference planning documents. There is also a booklet from the American Univac Users Association (AUUA) commemorating the society's 25th anniversary in 1980.

The Photographs and films series depicts equipment, facilities, and employees. There are two employee group portraits dated 1948 and 1949. One is labeled "The Original BINAC Crew"; those pictured include J. Presper Eckert and John Mauchly, among others. There is also a portrait of J.P. Eckert, as well as an image of him leading others on a tour of the Blue Bell laboratory. There are other images of staff giving visitors tours or demonstrations of the facilities and equipment. Several images depict the production shop, many of which include workers manufacturing and testing computer equipment. There are images of computer equipment, some of which are identified; some include men or women posing as office workers using the equipment. There is one small set of photographs that show a large computer being delivered to an office building on a flatbed truck, being attached to a crane, and workers hoisting the equipment up the side of the building using the crane. Most of the photographs are not dated; however, they appear to be from around the 1950s and 1960s. There are also five motion picture films about computers and computing featuring Sperry UNIVAC equipment.

The Objects series consists of three computer modules, four metal magnetic tape reels, a prototype of a disc file, and a Remington Rand brand plate. The UNIVAC computer modules are metal chassis with circuits, wires, and vacuum tubes, which as a unit are large and heavy. The disc file prototype was never manufactured, as the magnetic tape came out beforehand and rendered it obsolete. The UNIVAC disc file would have had the storage capacity of a megabyte, and the disks would have been about six feet in diameter.
