News clippings related to zoo events, facilities, animals, and activities. Most are loose clippings, but there are also four scrapbooks. One contains articles primarily from the early 1940s and from the late 1960s. One is of the first Zoo director, Gus Knudson. One contains Seattle Times articles from 1949-1956 written by Byron Fish while he worked for the zoo.

Records kept by and about zoo personnel including news articles, photos, academic papers, curriculum vitae, memos, correspondence, and administrative records.
