Journal of Contemporary Archival Studies

Documented individuals who do not live in conflict zones can usually access and use their records to migrate, begin new careers, enroll their children in educational institutions, and gain access to healthcare through mostly routine record-related procedures. However, these standard processes become impossible obstacles for refugees when they lose access to their personal records as part of their forced displacement. Though ever-present for refugees, these documentary burdens are compounded in times of societal crises and political upheaval—times when documentation is most critical. If archivists and archival scholars are to address these issues, it is important to understand the scope of …
