  • R 920 Biography, genealogy, insignia. A large collection of biography sources is maintained. Brief entry sources and those providing more extensive coverage are kept balanced, and both general biography and biography by field of endeavor are developed. The reference genealogy collection is the principal genealogy collection in the Library. (See also Section IX, Wyoming Collection and Section VII, Adult Nonfiction 920s.)

  • R 960 General history of Africa. Minimally developed.
  • R 970 General history of North America. The largest of the 900s collection, its major emphasis is on the United States, with some focus on the West. A general U.S. history coverage is maintained, but without attention to individual states. Sources on ethnicity need future development. Sources emphasizing Native American history are maintained.
  • R 980 General history of South America. Minimally developed.
  • R 990 General history of other parts of the world, extraterrestrial worlds. Sources on Australia/New Zealand, and the Polar regions are minimally developed.
