"When the Documents Section of the North Carolina State Library was organized between 1957-1960, this classification scheme was devised by the documents librarian, Sangster Parrott, for the Library's large collection of North Carolina public documents. Documents are arranged by state government agency and then by function. The scheme is partially adapted from the U.S. Superintendent of Documents Classification System which is used for Federal documents collections. The current edition shows agency name changes in general, but should not be relied upon as a complete history of a name due to the complex agency reorganizations, mergers, and dissolutions that have occurred since 1960."
