We discuss the inception and history of Behavior and Social Issues (BSI) and its predecessor journals, Behaviorists for Social Action Journal and Behavior Analysis and Social Action, as the journals approach 40 years of combined publication. In addition, we conducted a quantitative analysis of BSI's article impact, content, and frequent contributors to date. Data indicate that BSI has served as a valuable outlet to discuss and conceptualize applications of behavior analysis to a range of social issues. KEYWORDS: bibliometric analysis; history; social issues; behavior analysis Nearing 40 years of publication, Behavior and Social Issues (BSI) has covered a range of topics under the broad umbrella of social justice, human rights, and sustainability. It has been unique among behavioral journals in the topics addressed, open accessibility of the journal, and unique history that shaped the foci of the journal. This paper takes the opportunity to reflect on the evolution of BSI by providing both a description of the context and history that has shaped the content of the journal over the past four decades and a quantitative analysis of BSI's publication record to date.
