The collection is divided into four parts: official documents from Giessen (Germany), printed materials, correspondence, and research materials. The documents from Giessen are comprised of official marriage applications, marriage loan applications, and health authority documents under the Nazi government. (They range in date from 1936 to 1942, though most items are from 1942.) The documents include names of applicants and requests for information from other cities as well. Printed materials in the collection include Fernand Baldensperger's annotated copy of Gustave Lanson's Manuel bibliographique de la littérature française moderne, 1500-1900 (published 1911), as well as numerous literary pamphlets and essays (mostly reprints from journals) and political pamphlets and essays (mostly concerning World War II). The majority of the pamphlets were published during the first half of the 1940s, and many pamphlets contain inscriptions from the authors to Baldensperger. In addition, the collection contains two typed manuscripts (with corrections) of Baldensperger's La critique et l'histoire littéraires en France, au dix-neuvième et au début du vingtième siècles, as well as an additional (and probably unpublished) manuscript. Also included are various print materials from the early 1940s related to scholarly conferences and societies. The correspondence, primarily from the first half of the 1940s, pertains to both scholarly and personal matters, and it includes letters regarding the Institute of World Affairs (1940, 1941) and the publication of Baldensperger's La critique et l'histoire littéraires en France, au dix-neuvième et au début du vingtième siècles. Research materials include typed and manuscript timelines of literary history, corrections and additions to Baldensperger's works, and manuscript notes (occasionally with printed and typed articles) pertaining to his published works, works-in-progress, and a wide variety of literary subjects (various European literatures, Goethe, Balzac, Stendhal, Whitman, philosophy, poetry, etc.).
