Networks as interpretative frameworks: using co-citation analysis to explore large corpora of early modern letters

The analysis of co-citations, which occurs when two publications or authors are mentioned together in the same text, has long been established as a practice within scientometrics, particularly in the field of “science mapping”. However, historiography has shown less openness to utilizing co-citation analysis for distant reading purposes. To address this gap, this article presents a comprehensive methodology for applying co-citation analysis to extensive collections of historical documents, specifically 17th-century letters indexed in the ePistolarium database. In science mapping, co-citation serves as an indicator for tracking the development of scientific fields. Similarly, I employ co-citation to map the Dutch socio-intellectual landscape during the Scientific Revolution period (1623–87) and evaluate the strengths and limitations of this approach.
