Science in the Nineteenth-Century Periodical (or SciPer) offers a valuable resource for scholars interested in the cultural history of science. Here, readers will find a "searchable electronic index to the science content of sixteen nineteenth-century general periodicals," including references to science in fiction, poetry, travel writing, illustrations, and non-science articles. During the nineteenth century, periodicals had a large influence on cultural perceptions surrounding science, technology, and medicine, but "with an estimated 125,000 periodical and newspaper titles issued in England alone in the course of the century," navigating the sheer volume of material presents a challenge. SciPer provides an access point for a representative range of publications in a format that can be searched or browsed by a wide range of fields. This rich resource will likely be especially valuable to historians of science and literary scholars. First released in 2005 and now in its third published version, SciPer is a collaboration between the Centre for Nineteenth-Century Studies at the University of Sheffield and the Division of History and Philosophy of Science at the University of Leeds.
