The introduction presents the book’s core argument that twentieth-century Jewish archives were not just about the past but also about the future: We can look to a process whereby Jews turned increasingly toward archives as anchors of memory in a rapidly changing world. Jews in Germany, the United States, and Israel/Palestine all sought to gather the files of the past in order to represent their place in Jewish life and articulate a vision of the future. It situates these projects in the history of community-based archiving and archival theory and methodology, as well as Jewish history at large. It also dives into the ways we can see archive making as a metaphor for the broader patterns in modern Jewish history, as Jews sought to gather the sources and resources of their culture both before the Holocaust and especially in its aftermath.
