Conclusion
The collecting missions made an imprint on the postwar world of books and information. The OSS and military efforts to acquire open-source intelligence propelled advances in library and information science already underway. A number of those involved in wartime acquisitions became pioneers in this field. The program of acquisition offered a prototype for open-source intelligence gathering after the war. These missions also contributed to a growing orientation among American libraries toward internationalism, in which collecting foreign holdings was deemed essential to American power. For the most part, however, the collections themselves attracted little notice. With the Holocaust awareness of the late twentieth century, the acquisition of looted Jewish books was investigated by the Justice Department and President Bill Clinton’s Commission on Holocaust Assets. Looted and displaced books remain part of the unfinished business of World War II.
