Identities scholarship, in particular that focused on self-identities, has burgeoned in recent years. With dozens of papers on identities in organizations published in this journal by a substantial community, doubtless with more to come, now is an appropriate juncture to reflect on extant scholarship and its future prospects. I highlight three key strands of self-identities research in Organization Studies with particular reference to six articles collected in the associated Perspectives issue of this journal. In reviewing the contribution that work published in Organization Studies has made to debates on the nature of identities, how identities are implicated in organizational processes and outcomes, and the micro-politics of identities formation, I seek also to contribute to ongoing deliberations and to raise issues and questions for further research. I conclude with a call for increased efforts to integrate self-identities issues into the research agendas of sub-fields within organization theory.
