The correspondence documents Adler’s long-term freelance work for The Wiener Library. Among other activities this included the authoring of numerous reviews, expert reports, and articles for its Bulletin as well as contributing to research projects like the Library’s eyewitness testimony project.
Furthermore, light is thrown on Adler’s own academic work, primarily his ground breaking study on the Theresienstadt camp from 1955. The Library’s importance for its completion, attempts to place reviews in relevant journals or newspapers, the wide acclaim the study received, and Adler’s efforts to edit a second book on this topic are addressed in the letters. Briefly mentioned is also Adler’s withdraw from the International Auschwitz Committee.
