This article introduces the special issue 'Field as Archive / Archive as Field': a set of critical reflections on archival research and fieldwork in academic studies focused on space. The special issue asks, how might the experience of carrying out research in the archive and the field, with all its contingencies and errancies, be taken seriously as empirical material in its own right? In other words, rather than reducing the research process to an empirically insignificant instrument through which to access useable data, how could scholars and practitioners of architecture treat this work as the very stuff of the histories, theories, criticisms, and/or practices they produce? In raising these questions that remain relatively underexplored, especially in architectural research, this special issue works from the contemporary historical juncture that is marked by an increasing visibility of rhetorical and physical hostility throughout social and political affairs. Probing how this historical juncture might impact and be impacted by spatial research, contributors to the special issue explore these impacts through the markedly urban and architectural registers in which they take place, including heritage, infrastructure, displacement, housing, and protest. They, moreover, do so through a variety of contexts relevant to the journal's scope: Egypt, Zanzibar, Turkey, Greece, Iran, and Israel/Palestine.
