Through most of its history, Poultry Producers of Central California was said to the largest egg cooperative marketing association in the world. The collection contains material related to the activities of the Poultry Producers of Central California, including correspondence, interdepartmental memos, reports, publications, and advertising materials for eggs marketed by the cooperative under the name "Nulaids".

Headquartered in San Francisco, California, Poultry Producers of Central California (PPCC) was organized as an agricultural cooperative association in late 1916 to receive, grade, package, and market eggs received from its member-producers. Members entered into an exclusive marketing agreement to sell their eggs to PPCC; eggs were marketed under the brand name "Nulaids". By majority vote of its members in 1926, PPCC also established a Feed and Supply Department to sell poultry feeds and farm supplies to its members. The association also included a credit union, Federal Credit Union. Membership in the credit union was open to members and employees of PPCC, as well as to their immediate family.
