Correspondence, clippings, photoprints, articles and files reflect Brookfield's interest as a Florida Keys lodge host, writer, environmentalist, fisherman, marine archaeology enthusiast, treasure hunter, and real estate investor. Correspondence includes letters on the early efforts of the Audubon Society to secure a portion of the James Deering estate as an Audubon bird sanctuary. Photographic prints are of the Bahamas, Elliott Key, and Florida, and date from the 1930s-1980s; most are identified.  Also included is a typed transcript of TMS Winchester's 1694 log book and the Captains log of the Dunkirk.
