The collection consists of the correspondence files of Frederick Hanley Seares. While roughly one half of the papers deal with administrative matters of the Mount Wilson Observatory, the remainder cover his scientific work. There are also some manuscripts, notes and notebooks (Boxes 19-21) related to Seares's research activities.

The collection deals primarily with the professional activities of Olin C. Wilson, who was most active from the mid-1930s into the 1980s. Wilson corresponded frequently with astronomers from a variety of universities in the United States and abroad, and the collection is representative of the deeply international and collaborative nature of astronomical and astrophysical research in the second half of the twentieth century. It also contains valuable and insightful material related to the schism between Mount Wilson and CalTech in the 1970s and 1980s, and the near-demise of Mount Wilson during that decade.

Three letters sent by Brantz Mayer in California to his wife Cornelia Poor Mayer in 1872. In the first letter, dated June 17 and sent from San Francisco, Mayer writes of speaking to various individuals about his plans to travel to Yosemite, of other groups who have traveled there, and notes that "about 999 Japs came out of the Hotel [the Grand Hotel, San Francisco] today, from the just arrived China Steamer." In the second letter, dated June 23 from Calaveras County, California, he writes of traveling from San Francisco to Murphys, California, with the Sawyer family and others. In the final letter, dated June 28 in Yosemite Valley, Mayer writes extensively of his travels from Calaveras to Yosemite, of his encounters with locals and tourists, of the scenery, of transportation in the Valley, of expenses, and his conclusions that "as to this Yosemite Journey, I have to observe that it is so fatiguing when quickly & cheaply made, that I might almost say a poor man has no right to undertake it." The letter was completed in San Francisco on July 2, and mentions William W. Belknap and Reverdy Johnson, Mayer's general travels in California, and of Mayer's being "quite fatigued yet, and very generally demoralized by the journey."
