For over a decade this work has taken me into the archives, onto the grounds of the camps themselves, and through the survivor testimony and documentary record of the Nazi persecution system. Understanding how the camps operated, who was held where, what records survive, and how to cross-reference fragmented documentation across national and institutional archives is the foundation for every case I investigate. Whether you are tracing a prisoner, a survivor, a liberator, or a victim of war crimes, a paper trail and context exists.
