The James M. Gwin Collection contains approximately 50,000 items of poultry information resources. It consists primarily of business correspondence pertaining to several poultry associations, catalogs from poultry equipment manufacturing firms, documents about early breeders in the poultry industry, egg and poultry legislation, papers on industry meetings held in various states of the United States, and miscellaneous publication clippings related to the egg and poultry industry.

The Edward Fred Knipling Papers are part of the Screwworm Eradication Program Records in the Special Collections of the USDA National Agricultural Library. The Knipling papers cover the areas of entomology researched by Knipling during his career with the U.S. Department of Agriculture (USDA), including his early research on the screwworm and the eradication efforts in Curacao, Netherlands Antilles, and the Southeast United States in the 1950s. Knipling's research included parasite control methods and studies on the boll weevil, fruit fly, tsetse fly, European corn borer, and various species of ticks and moths. In addition, the collection reflects Knipling's continued activity in entomology after his 1973 retirement from the USDA. Materials include correspondence, publications, manuscripts, reports, photographs, research data, notes, speeches, awards, artifacts, and biographical information.
