Casefiles are a common source for scholars in social history and related fields. They have, for instance, been crucial in the development of micro-historical approaches to the Holocaust. In recent years, they have been taken into consideration to examine humanitarian responses to and experiences of forced displacement. In this post, I would like briefly to discuss some of the potential, limitations, and challenges that this material entails. To do so, I will examine a specific set of sources: the casefiles of a group of more than 1,000 young Holocaust survivors who were resettled to Canada in the aftermath of the Second World War through a project sponsored by the Canadian Jewish Congress (CJC). These young people were predominantly Eastern European teenage boys who, at the time of application for a visa, lived in Displaced Persons (DP) camps, children’s homes and with foster families across Europe.
