The Public relations series has been arranged into five subseries: Client/project files; Scrapbooks; Publicity clippings; Speeches; and Department files.

The Client/project files subseries consists of press releases, photographs, trade literature, and some correspondence documenting Loewy's role in helping to create the modern consumer society and his work on more than 200 projects for clients such as Exxon, Shell Oil, and Coca-Cola. The materials date from 1934 to 1981, with a majority of the materials dating from 1947 to 1963.

Scrapbooks contain articles that appeared in magazines, newspapers, and trade publications. Topics include the Avanti, stores (interiors and exteriors including Gimbels, Lord & Taylor, Foley's, and Wanamaker's), dinnerware (Fostoria, Limoges, Lucent Corp, Rosenthal), fabrics, furniture, cars (Studebaker and Avanti as well as Loewy's personal automobiles), Snaith/Project Home, supermarkets, housewares, transportation (including Pennsylvania Railroad, TWA, Panama Lines, Air France, United Air Lines), and packaging.

Several scrapbooks contain clippings pertaining to Loewy's public appearances and speeches, and his social life, a valuable resource since most of Loewy's business correspondence during the 1930s and 1940s had been destroyed. The materials date from 1934 to 1970. Volume 15 is missing.
