The papers consist of Francis Pease's research papers. It contains correspondence, manuscripts, Pease's notes (including his work notes, many of which contain various drawings and diagrams by him), reprints, photographs, etc. Topics covered in the collection are numerous and include the Mount Wilson Observatory, the Yerkes Observatory, astronomy and astronomers. The majority of it relates to Pease's research on the speed-of-light (highlighting his manuscript with Albert A. Michelson), Ether drift, his observations of the Moon, the Sun, Jupiter, star diameters, galaxies, nebulae, as well as his work on interferometers, and the design and construction of telescopes.
The collection includes correspondence, manuscripts, printed material and ephemera all related to astronomer Francis Gladheim Pease, his astronomy work, and the telescopes he designed. There are 13 letters by George Ellery Hale as well as a copy of an offprint of "Building the 200-Inch Telescope" by Hale (originally published in Harper's Magazine, November 1929). There is an offprint of "The Spectra of Four of the Temporary Stars" written by Pease and Walter S. Adams (published in Contributions from the Mount Wilson Solar Observatory No. 87 in 1914). The correspondence includes several prominent individuals including: Giorgio Abetti, Walter S. Adams, John A. Anderson, Andrew Carnegie (typed copy), Edward H. Davis, Elmer Grey, George Ellery Hale, Fred E. Harvey, Herbert E. Ives, Thornwell Jacobs, George Wharton James, Helen Keller (photocopy of letter), Albert A. Michelson, Robert A. Millikan, James R. Page, F. E. Wright, and the Bausch & Lomb Optical Company. There is also one letter addressed to Thomas Edison. The manuscripts include several items by F. G. Pease including a "Figuring Book" which contains his work on various telescopes and contains blueprints and a manuscript entitled "Notes on a 25-Foot Reflector."

Pease including a "Figuring Book" which contains his work on various telescopes and contains blueprints and a manuscript entitled "Notes on a 25-Foot Reflector." The ephemera is made up of printed offprints, a blueprint of the telescope at Mt. Wilson, newspaper clippings, miscellaneous items, and material from several websites (Caltech Astronomy, JPL, and Mount Wilson; printed 1999-2001) regarding Einstein, telescopes, Mt. Wilson, the Palomar Observatory and the Comet Hale-Bopp. The photographs include a portrait of George Ellery Hale (1929), three photographs of the construction of the telescope at Palomar Observatory (1937), and a photograph of Albert Einstein with Charles St. John, Ferdinand Ellerman, Walther Mayer, and Edwin Hubble on the steps outside the 150-foot tower telescope during Einstein's second visit to Mt. Wilson (January 1931: the Huntington has another copy of this photograph: COPC 2787). The collection is arranged alphabetically by author: correspondence and manuscripts, folders 1- 32; followed by ephemera, folders 33-41.
