The Stephen Sondheim Society Archive documents the life and work of musical theatre composer and lyricist Stephen Sondheim. The core of the collection was collected by antiquarian bookseller and Sondheim enthusiast Peter Wood- his collection later passed to the Society. Additional material has been added since, filling in gaps in the Peter Wood collection and documenting productions and publications that have occurred since it was transferred to the Society.

Both parts of the Collection contain a range of material on Stephen Sondheim and his work- notably programmes, leaflets, posters and press cuttings. There are also journals, books, audio visual material and collectables. The Collection dates from Sondheim's earliest work to the present and will continue to be added to as his works continue to be performed. There are also documents relating to the work of the Society itself, notably the Stephen Sondheim Society Student Performer of the Year awards (SSSSPOTY).
