Scientific disciplines build on social structures, such as scholarly associations and scholarly journals, that facilitate the formation of communities of specialists. Analyses of such social structures can thus also be used to shed light on the morphogenesis of scientific specializations. The authors analyze how two journals of the American Educational Research Association, the Review of Educational Research and the American Educational Research Journal, organized communication around education in the period between 1931 and 2014. The authors focus on three interrelated aspects: (a) the changing structures of authority and authorship, (b) the national-versus-global orientation of these journals and of the association, and (c) the features of the citation networks of both journals and the ties between education research and other fields of research, especially psychology and sociology. The authors' analyses of these interrelated aspects of the communication process enable them to provide an outline of the morphology of the community of education researchers and to raise reflectivity about the social conditions that control education research.T he 19th-and 20th-century rise of disciplinary specializations within the field of science depended on two kinds of social structures. The level of structural support for scientific research increased markedly after the expansion and reformation of the university system, which was first realized in Germany (in the so-called 678836R REXXX10.3102/0091732X16678836Review of Research in EducationVanderstraeten et al.: Scholarly Communication in AERA Journals research-article2016 Vanderstraeten et al.: Scholarly Communication in AERA Journals 39Bildungsuniversität) but quickly spread to other countries. New occupational roles in universities increased the time available for scientific research, and scholars became able to make careers in research. But the rise of scientific specializations also depended on the formation of specialized scientific communities-networks of individual specialists. Such communities built (and still build) on social structures that enable the intensification of interaction, the development of shared expertise, the articulation of conventionalized problems and approaches, and so on (see Abbott
