"The need for a scheme/system to classify state documents has become increasingly apparent as more and more emphasis has been placed on libraries to acquire and service this important body of material. Because of the diversity in library organizational patterns, documents librarians could probably never agree on one system for classifying state documents. However, those libraries which maintain a separate collection of state documents and also a separate federal documents collection classified by the Superintendent of Documents Classification scheme will be interested in the classification scheme for State of Illinois documents used by the Documents Section, Library, University of Illinois at Chicago Circle. By applying similar principles, this scheme is easily adaptable for publications of other states. Although the scheme is now presented in nearly as complete a form as possible, it is still subject to any changes made necessary by Illinois government organizational changes."
