The Rocky Mountain Online Archive is your source of information about archival collections in Colorado, New Mexico and Wyoming. Specialized guides, called finding aids, give detailed descriptions of primary source materials located at twenty-seven different repositories. Search the finding aids to discover what historical materials are available for study and where those collections are located.

The Rocky Mountain Online archive is managed by University Libraries at the University of New Mexico. Leadership is provided by representatives from each of the three participating states.
