To examine how communication scholars have incorporated the concept of social capital originating from other disciplines, we first analyzed citation patterns among social capital–related journal articles, book chapters, and books extracted from Communication Abstracts. Moreover, we investigated whether and how communication scholars have cited three pioneering scholars in this area, that is, Robert Putnam, Pierre Bourdieu, and James Coleman, to identify aspects of social capital that have either been emphasized or overlooked. Based on the analyses of 171 journal articles, books, and book chapters, we found that the translation of the concept of social capital into communication research has been driven and dominated by a small group of political communication scholars. The results of our content analysis demonstrate that the prominent players in social capital research in the communication field distinctly favored the work of Putnam over those of Bourdieu and Coleman. The implications of these findings for communication research are discussed.
