This paper extends Critical Race Feminista Methodological (CRFM) approaches by contending that "convivencias" -- the coexistence necessary for creating relationships in the field -- are an integral part of engaging research collaborators within educational historical research. Drawing on oral histories with Chicana/o librarians, personal collections, and archival sources, I outline the "convivencias" I shared with librarians that span across spatial and temporal dimensions. These interactions were centered on recollecting, remembering, and learning about the activism within Latina/o/x children's literature and librarianship's history. "Convivencias" across space were possible through diverse interactions, such as in-person meetings, phone conversations, video conferences, and emails. "Convivencias" across time are represented by the continuity of sustained efforts to advance social justice in librarianship across multiple decades. The conceptualization of "convivencias" across space and time emerged as a CRFM tool that aims to center seldomly documented narratives of activism essential for fostering connections, cultivating community memories, and nuancing historical educational research.
