The collection includes seven volumes of scrapbooks containing clippings on current affairs roughly between 1939 and 1950 with particular reference to the trials of the German War Criminals at Nuremberg and the state of Germany after World War II. Also, general items on President Franklin Roosevelt and U.S. foreign policy. There are several complete copies of newspapers folded and inserted in the scrapbooks. The second and more important part of the collection consists of typescripts of Dr. Pfeiffenberger's writings. These occupy one and one-half manuscript boxes (Boxes 4 and 5).

Klein, and Dr. Klavehn-Berndt (there are many changes and notes in script, and this item is accompanied by another typescript of approximately the same size on the same subject), and several other items.
