Accession 90-105 (1920s-1970s): These records constitute the morgue files for the Science Service, and as such contain past articles, press releases and other materials produced by the Science Service. In addition are supplemental photographs, news clippings, scientific papers and articles, obituaries and related topical information. Many of the topics document the area of physics.

Accession 06-134 (1921-1974): This accession consists of photographs, captions, and press releases related to modern physics, with emphasis on atomic physics and accelerators. These files were originally part of the research files compiled by and for journalists who worked at Science Service from the 1920s through the 1960s. Most folders contain a mix of editorial correspondence, press releases, newspaper clippings, brochures, and photographs. Folders on physics facilities built in the 1950s and 1960s tend to contain primarily news releases, clippings, and copies of Science Service stories. Many folders assembled during the 1930s contain issues of the Daily Mail Report. Some of the photographs in these files were taken by members of the Science Service staff, especially Fremont Davis; most were supplied by companies, universities, and government agencies.

Accession 13-034 (1927-1970): This accession consists of Science Service subject files pertaining to medical science, chemistry, chemical technology, and physics. Materials include correspondence and memoranda; news releases; clippings, photographs and negatives; articles, reports, research papers, and related topical information. Physics topics include accelerators, cyclotron, electricity, atom smashing electrical guns, betatrons, high coltage apparatus, Enrico Fermi, Harold C. Urey, and Robert J. Van de Graaf.
