Geographic Information Systems and Book History

Scholars working in the multidisciplinary field of book history pose diverse research questions, work with numerous sources of data and information, and employ a variety of analytical methods and tools. Geographic questions have been considered by book historians, notably since the groundbreaking work of Lucien Febvre and Henri-Jean Martin in the 1950s. Geographic information systems (GIS) technology, which was developed in Canada in the 1960s, was initially devised to support new methods of analysis and visualization in the physical and life sciences relating to spatial conditions, patterns, trends, and projections. Since the late 1990s, social scientists have used GIS increasingly, and, since the early 21st century, humanities scholars have also begun to use GIS as a result of digital and spatial turns within their fields. The application of GIS as an analytical method to investigate research questions in book history, first suggested in 1997, is now employed across a range of scholarly endeavors. Examples from the sciences that illustrate the required data structures, as well as the scope and analytical power of GIS, illuminate the development of geographies of the book. Such examples also illustrate the types of questions for which GIS is appropriate for advancing knowledge. Limited training for book historians in the application of GIS, along with the complexities of the technology, have resulted in the need for partnerships with quantitative researchers. These collaborations are increasing understanding of the spatial dimensions of book and print history. In addition, new programs of study in digital humanities, and initiatives of innovative scholarly societies, are helping to forge a generation of technologically trained scholars to propel the field of book history further.
