The Paul R. Hill Collection contains material relating to the NACA/NASA/Langely career of Paul R. Hill from 1939-1970. Materials include books, papers, newspapers, lantern slides, NASA publications and memos, overhead sheets, and notes from presentations and talks.

Many photographs portray Hill's design for a personal flight device. Other drawings reflect planetary orbits or space station models. Presentation notes accompany a few slide folders.

The collection also consists of various publications and papers written by Hill and other authors. Many of these publications are declassified official NASA reports, and others are NASA publications from award ceremonies and department memorandums. Wherever possible, bibliographies at the folder-level are included in the "Contents List" below. Other publications include drafts of papers reviewed by Hill. A number of books were removed from the collection to be catalogued (see "Separated Materials" below).

Also included in this collection are personal papers of Paul R. Hill. Some of these items include his 1936 voter registration, work evaluations, and correspondence regarding his personal projects. Newspaper and magazine clippings kept by Hill are also included in the collection.
