When researchers combine scientific analysis with historical archival research, they are able to provide us with exciting insights that only such an interdisciplinary approach could produce. For instance readers may be familiar with science undergraduate Linnda Caporael's 1976 examination of 17th century Salem, which led her to hypothesize that ergot poisoning may have played a role in the Salem Witch Trials. In similar style, this article, which appeared in the open source science journal PLOS One, uses archival evidence - specifically Zou Zhe, reports from local officials to the Chinese emperor - to map out the location and duration of droughts in China between 1689-1911. This information can be used to predict and prepare for future drought patterns in the region. The article is fascinating, can be used in both history and geography classrooms, and serves as a model for scholars interested in pursuing such interdisciplinary approaches.
