Collective biography uses researchers' written memories about a set of experiences as texts for collective analysis. As a feminist approach to research, collective biography draws centrally on the idea that significant memories are critical in the constitution of the self, and maintains that in analyzing memories collectively, researchers can begin to tap into wider social processes and structures. Though rarely used in geography, collective biography could be useful in data collection and analysis for geographers. In this paper, we provide a brief history and description of collective biography. We situate collective biography in relation to life writing methods. We then identify a set of attributes that mark collective biography as a distinct research approach. In closing, we ref lect on our experiences working with collective biography.Collective biography is an approach to research that seeks to address the constitution of the subject. Through a shared analysis of a set of systematically recalled memories, researchers are able to show the effects of structural, systemic, and affective processes on the emergence of particular subjects, such as the neoliberal subject, the gendered subject, and the academic subject (e.g. Davies et al. 2005Davies et al. , 2006Somerville et al. 2003). The approach as originally developed by feminist sociologist Frigga Haug and her colleagues in Germany during the 1980s focused on memory work ( for English translation, see Haug et al. 1999). Women recalled moments in their pasts that brought into focus what type of sexualized subject they were being disciplined to be. Feminist education scholar Bronwyn Davies along with her students and colleagues in Australia extended this methodological work and produced an extensive body of research on neoliberalism and gendered subjectivities (see e.g. Davies and Gannon 2006a). Since the early 2000s, collective biography has further developed using experimental, creative, and poststructural writing practices (e.g. Gale et al. 2012;Gannon et al. 2014;Speedy et al. 2010) and has begun to spread into other disciplines.But what about geography? Can collective biography provide a way to generate data and conduct analysis to produce more nuanced understandings of the topics in which geographers are interested? Methodologically, what does collective biography offer that other approaches do not? In this paper, we first describe the specifics of collective biography as an approach to research. We next situate collective biography in relation to other qualitative approaches commonly used by geographers with particular attention to the similarities between collective biography and life writing. Then, we discuss nine hallmarks that we have identified with illustrations from our work. We close with suggestions on how to extend collective biography to conceptual interests in space and place, considering its use as a methodology with potential.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs Li...
