The collection begins with Butscher's correspondence. He was able to get information from a wide variety of sources. Some notable people in Plath's life are Richard Norton, Cyrilly Abels, Wilbury Crockett, and Myron Lotz, amongst many, many others. The collection also holds Butscher's research notes and manuscripts for his 1976 biography, Sylvia Plath: Method and Madness as well as his 1977 collection of essays, Sylvia Plath: The Woman and the Work.
The collection also includes photocopies and printed versions of Plath's poetry and prose, fragments of Letters Home, as well as articles and essays about Plath. The collection includes 15 photographs of Plath, of her children, of places she lived, her grave, and the Wellesley High track team.
