Consists of correspondence and legal documents relating to Buck's publishing activities from 1928 to the early 1950s, when she was a client of the David Lloyd Literary Agency. The records demonstrate Lloyd's role as a liaison between Buck, her publisher, John Day (often represented by Buck's husband, Richard J. Walsh), and many publishing houses and popular magazines. The documents concern, among other things, translations, foreign publishing rights, and serialization of Buck's novels, short stories, and articles. Thirty-six different languages are represented in the collection.

Much of the collection consists of inter-agency correspondence between Lloyd and the London firm of A. P. Watt & Son regarding Buck's foreign interests, as well as correspondence with magazines such as Red Book, Cosmopolitan, Saturday Evening Post, and Ladies Home Journal relating to serializations of Buck's works. The collection also contains numerous legal documents, such as memoranda of agreement, financial records, and correspondence regarding film and stage rights, and the works of John Sedges, a pseudonym for Buck. Also included are materials relating to Buck's withdrawal from the agency and the termination of their association in 1957, when she joined Harold Ober Associates. In addition, there are some correspondence and permanent registers of other authors represented by the David Lloyd Agency.
