The Irwin Gordon papers are composed of records generated by Gordon during his 35-year career at RCA Laboratories. They encompass laboratory reports and findings, as well as a number of papers he authored. They also include background and research materials, such as journal articles and technical reports, and manuals for radios, televisions, and tape recorders. Several awards and an invention disclosure reflect his achievements at RCA Labs, and a small collection of ephemera – RCA flight operations, concessions tickets from lab picnics, a Christmas card from RCA Japan, and “bag-velopes” – offers a glimpse of everyday life at the corporation.

Forty-seven of Gordon's lab notebooks (1952-1987) can be found in Record group 26.

Jackson Hunsicker (1948-2017) invented the Memo Mate in the mid-1990s. It was a small personal recording device that could store up to twenty seconds of audio. The Memo Mate was marketed as a handy way to remember appointments, phone numbers, directions, and the location of a car in a large parking lot. The Memo Mate was a successful invention, selling close to 10 million units. Hunsicker's papers on the patenting and marketing of Memo Mate document the typical process and pitfalls of patenting and marketing by a lone inventor. The collection consists of the legal correspondence of the patent application process and subsequent contractual disputes, along with schematics and designs, and possible names and logos. Hunsicker’s invention represents a demonstration of the patent process as well as a contribution from a woman inventor to the field.
