A bibliography of United States Decennial Census Publications for 1790-1970 and a reel index for the microform collection of these publications.

Montana: A History of Two Centuries first appeared in 1976 and immediately became the standard work in its field. In this thoroughgoing revision, William L. Lang has joined Michael P. Malone and Richard B. Roeder in carrying forward the narrative to the 1990s. Fully twenty percent of the text is new or revised, incorporating the results of new research and new interpretations dealing with pre-history, Native American studies, ethnic history, women's studies, oral history, and recent political history. In addition, the bibliography has been updated and greatly expanded, new maps have been drawn, and new photographs have been selected.
