This folder contains correspondence relating to Edison's membership and activities in social clubs and professional societies. Among the documents for 1910 are several letters from the American Institute of Electrical Engineers, to which Edison donated a diary by Samuel F. B. Morse. There are also several invitations to the annual banquet of the Ohio Society of New York, which Edison declined on account of his deafness. In addition, there are letters from the National Electric Light Association, the Committee of One Hundred of the American Association for the Advancement of Science, and other professional societies; automobile and booster clubs; and religious, civic, and philanthropic organizations. Some of the items contain marginal notes by Edison.

Approximately 10 percent of the documents have been selected. The items not selected consist primarily of announcements, invitations that Edison declined, and correspondence from organizations in which he did not participate.
