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.
