The following section contains magazine articles, newspaper clippings, pamphlets, transcriptions, and manuscripts written by authors other than Snow. These materials are arranged into five subsections: subject files, newspaper clippings, printed materials, documents, and pamphlets. They constitute a collection of material, pertaining to historical events and personalities, which Snow gathered throughout his career as background information for his writings. Some items were annotated by him and some folders include a small amount of correspondence related to the subject, manuscript fragments, and a few interviews. The contents of these folders were retained in the manner in which they were received. Folder headings were retained unless noted otherwise. Folders 624 through 632, and the Printed Material section's folder headings were assigned by the University Archives and are arranged alphabetically. Newspaper clippings and magazine articles regard to events and personalities of the time. Some folders contain news releases from various news bureaus, notes and manuscript fragments.
