IsisCB Explore

IsisCB Explore is the new open-access search interface for the History of Science Society's ISIS Current Bibliography.  It includes nearly 200,000 interlinked bibliographic citations to books, chapters, articles, dissertations, and reviews from 1974 to present.  This site is supported by the History of Science Department, the History of Science Collections, and the History of Science Society.  Prof. Stephen P. Weldon, the editor of the Isis Bibliography, received a grant from the Alfred P. Sloan Foundation to create this new service.  This is the first time the data has been made available to scholars worldwide in an open access format, which requires no login to use.

Commbase: A Database of medieval commentators on Aristotle and Peter Lombard's Sentences

Steven J. Livesey Prosopography

Prosopography is a form of historical inquiry that investigates common features of a group of historical figures through a collective study of their biographical data. By its very nature, it differs from pure biograph­ical research in the sheer quantity of the data accumula­ted and analyzed, and from political and other forms of history in that it seeks to investi­gate those political structures through the personal rela­tionships of the individuals they comprised. From its inception in the late nineteenth century, prosopographical research has contributed greatly to historical knowledge, particularly in societies where the political structures under investigation were still in a rudimentary state of develop­ment [Stone (1972) and Beech (1976)].

The use of computers in historical work is now more than a generation old. One of the pioneer­ing studies for the Middle Ages was conducted by T. H. Aston et al. (1977, 1980), who analyzed A. B. Emden’s biographical registers of medieval Oxford (1957-59) and Cambridge (1963) scholars. Their research displayed, among other things, the extracurricular fortunes of medieval university graduates from the thirteenth through the fifteenth centuries, research that has been the basis of a continuing controversy over the funding of medieval English education. Subsequent prosopographical studies, like Jacques Verger’s work (1986) on universities of the Midi or Christine Renardy’s analysis (1981) of universities in the diocese of Liège, have tended to focus on a particular university or region and analyze the university structure through the prosopo­graphical data of its graduates. In projects such as these, institutional records are scruti­nized by comparing their picture of the institution against that emerging from the lives of university members.

The prosopographical database upon which I am working focuses on the Middle Ages, and in particular on the authors of two fundamental groups of texts: commentaries on Aristotle’s works, and commentaries on a theological text with significant scientific content, Peter Lombard’s Sentences. During the twelfth and early thirteenth centuries, these two groups of texts became the primary pedagogical tools for the two major faculties of nascent European universities. Students and masters alike were expected to show their familiarity with and elaborations upon both Aristotle and the Sentences. The database takes its unifying structure from the literary products of the Arts and Theology faculties, and seeks to investigate the institutional and biographical components of these products.

The database is comprised of eleven related tables, organized in the following way:
