Scholars focus on the social nature of academic writing to refine an understanding of feedback interactions in higher education. However, studies on the various sources of feedback -- feedback networks -- have been scarce, particularly during the initial years of doctoral education. Using a qualitative case study approach, multiple sources of feedback for four students in one doctoral program in the United States were identified in line with broader trends focusing on feedback as a social practice. Informed by the academic socialization framework [Duff, Patricia A. 2012. "Second Language Socialization." In "Handbook of Language Socialization," edited by Alessandro Duranti, Elinor Ochs, and Bambi B. Schieffelin, 564-586. Malden: Wiley-Blackwell], this study aims (1) to navigate the landscape of graduate feedback, including interactions beyond class as well as oral and written feedback, and (2) to elucidate the socialization process. Findings suggest that academic writing development is defined as how feedback is situated within disciplinary, academic communities of interaction. This article describes how the larger network of feedback creates the types of interaction that characterizes the community.
