The George Platt Lynes diaries consist of diaries and datebooks which record his activities and thoughts, starting with a journal of Lynes' first trip to Europe in 1925 and ending with entries in a pocket datebook just weeks before his death in 1955. Though his early and later years are well documented, there are no diaries for the years 1931-1941. Accompanying the diaries are a few odd pieces of personal memorabilia, including a notebook of dinners given during the early 1940s and printed versions of writings by Glenway Wescott form the early 1920s.
