This Special Issue of Arts investigates the use of digital methods in the study of art markets and their histories. As historical and contemporary data is rapidly becoming more available, and digital technologies are becoming integral to research in the humanities and social sciences, we sought to bring together contributions that reflect on the different strategies that art market scholars employ to navigate and negotiate digital techniques and resources. The essays in this issue cover a wide range of topics and research questions. Taken together, the essays offer a reflection on what takes to research art markets, which includes addressing difficult topics such as the nature of the research questions and the data available to us, and the conceptual aspects of art markets, in order to define and operationalize variables and to interpret visual and statistical patterns for scholarship. In our view, this discussion is enriched when also taking into account how to use shared or interoperable ontologies and vocabularies to define concepts and relationships that facilitate the use and exchange of linked (open) data for cultural heritage and historical research.
