In the Arthur and Elizabeth Schlesinger Library on the History of Women in America at the Radcliffe Institute for Advanced Study, Harvard University, there is a small collection of materials related to Sylvia Plath by the poet Jean Valentine. The finding aid is online here.
The following description is from a subseries of prose materials: 6.8-6.9. Plath, Sylvia, 1995-1998, n.d.: letter to the editor of The New Yorker, an unpublished piece titled "Notes on Sylvia Plath", and clippings about Plath.
If anyone out there has seen this material, please let me know. Otherwise, I'll try to get access to it one day.
