Record linkage, as a research topic, is approaching its semicentennial anniversary. Over its lifetime--and specifically, during the past few decades--record linkage has become a cross-disciplinary research field. However, as often happens when different scientists approach the same problem, separate bodies of literature have grown concurrently. Gathering together the research related to record linkage requires an understanding of its many alternative names: entity linking, entity resolution, probabilistic matching, duplicate detection, data linking, and, of course, record linkage, among others. In addition, subfields related to record linkage have also developed, such as privacy preserving record linkage (PPRL), informed consent for record linkage, temporal record linkage, and differential record linkage. This paper will attempt to provide as comprehensive a review as possible of the literature related to record linkage across its many disciplines.
