Many cities and counties have written their histories. These can be good secondary resources, and occasionally these may serve as primary resources if they include first-hand accounts of life in a place. To locate county histories in Discover Local, search the words "county history Oklahoma" (without the quotes) in the "Any field" category, limiting "Material Type" to "Books." Another good way to locate a county or town history is to search for that place in the subject category.
