Public relations (PR) and organizational communication (OC) are two related fields of research in the larger discipline of communication studies; nevertheless, they developed separately. Inspired by Christensen and Cornelissen (2011), who argue that the fields of corporate communication and organizational communication could cross-fertilize if they acknowledged their common ground, this article has a threefold aim: first, to explore the main gaps between PR and OC; second, to identify ways of bridging those gaps through a systematic comparison of the axioms underlying PR and OC, in contrast to Christensen and Cornelissen, who mainly focus on enriching corporate communication with ideas from OC; and third, to argue that the field of German-speaking communication research, which draws to a large extent on holistic social theories (e.g., Habermas, 1984, 1987; Luhmann, 1995; Schimank, 1996), offers the means of bridging PR and OC. We also argue that it is worth exploring potential bridges between PR and OC in German-speaking Forum
