The following four boxes are made up of correspondence (arranged alphabetically by author) and manuscripts (arranged by topic). The sub-series includes the same authors that can be found in the larger Adams Collection boxes. The manuscripts (which include reports, speeches, articles, press releases, etc.) are written by several different people including Walter Adams, George Ellery Hale, Albert Michelson, F. E. Wright and many others. The majority of these manuscripts are related to astronomy and Mt. Wilson. There is one manuscript about Albert Einstein's visit to Mt. Wilson. There is also one folder of photographs and one folder of ephemera. There is a photograph of Albert Einstein with Humason, Hubble, St. John, Michelson, Campbell and Adams (circa 1931).
