In January, 1962, the University of Wyoming's Department of Geology published the first issue of Contributions to Geology (vol. 1, no. 1).
That single-issue volume was followed by 31 two-issue volumes and four special papers.
The final issue of Contributions to Geology appeared in March, 1998 (vol. 32., no. 2), and was redesigned into Rocky Mountain Geology.
Back issues of nearly every volume are available, and we continue to sell them at their original prices, from $1.50 to $10 per issue. All issues are also available electronically on GeoScienceWorld where you can view and download the entire archive.
