This folder consists primarily of correspondence from Edison's friends and acquaintances. Several of the letters contain reminiscences about Edison's early career in telegraphy. There are also letters from current associates covering a wide range of subjects. Included are invitations, requests for photographs, charitable and commercial solicitations, and death notices. Among the correspondents for 1911 are Sigmund Bergmann, William F. Brewster, Henry M. Byllesby, Alfred A. Cowles, Henry L. Doherty, Samuel Insull, Robert T. Lozier, Anne Morgan (daughter of J. P. Morgan), and Arthur Williams.

More than 90 percent of the documents have been selected. The documents not selected consist primarily of duplicates and unsolicited requests for biographical information.
