The bulk of the Eleanor Troy Williams Collection is comprised of correspondence and scripts, including those written by other people, which she wished to keep together. Williams’ correspondence with numerous family and friends in Maine, New York, and elsewhere dates from 1929-1942, and includes post cards, birthday and Christmas cards, telegrams, and envelopes. Script materials for Pages of Romance contain cast lists; where available the actors have been listed, and used as entry points to the collection. Material relating to the Town Hall, Inc. includes invitations and programs. Among the personal materials are Williams’ resumes (1928-1944), finance records (1931-1937), programs for performances (1937), and numerous sayings and notes. For the post-war period, she gathered information on public opinion and free-lance opportunities (1944-1946).

Williams was also an illustrator. Among the drafts, painted drawings of costumes, and sketches, are A Quiet Little Summer on the Coast of Maine, and a series of illustrations of the Joe Wyer Stories she collected from Chebeague Island, Maine.
