The Smith College Archives holds the Sylvia Plath Hughes Papers (1950-2001, bulk 1952-1963). These are papers primarily “contain biographical information, photographs, press releases, and writings by and about Plath.” A note on the finding aid indicates that most of the materials in the collection are previously published.
Some of the material by Plath in this collection is likely uncollected, for example the press releases from 1952 and 1953 for the Smith College Press Board. For those with access to Stephen Tabor’s Analytical Bibliography and to either microfilm or back issues of the Daily Hampshire Gazette, you could read Plath’s reviews of events that the DHG published during her time as Press Board correspondent.
The collection does contain some monographs, including a 1965 copy of Ariel, The Colossus and Other Poems. These are likely first editions. Additionally, there is a copy Stings, a limited edition facsimile of Plath’s drafts for the poem with an essay by Susan R van Dyne and of Ingrid Melander’s The Poetry of Sylvia Plath: A Study of Themes from 1971.
The finding aid to the collection is online here. There is a related material note: “Additional information about Plath's Smith College experience may be found in the Class of 1955 records, the English Department records, student publications of the time, and a subject file on Plath which is available in the College Archives Reading Room. The primary source for Plath material at Smith College is the Mortimer Rare Book Room.” All of these resources will be useful to researchers of Plath.
