The poems in typescript and/or proof are:
"The Snowman on the Moor", "Sow", "Ella Mason and Her Eleven Cats", and "On the Difficulty of Conjuring up a Dryad" from Poetry 90 (July 1957: 229-236).
"On the Decline of Oracles", "The Death of Myth-Making", and "A Lesson in Vengeance" from Poetry 94 (September 1959: 368-371).
The correspondence is between Plath and editors Karl Shapiro and Henry Rago. Also included are a couple of letters about Plath. In the letters held in the archive for the period between 1956 and 1961, Poetry apparently rejected only one submission from Plath, and that was "Poem for a Birthday".
The letters to Shapiro and Rago are cordial and professional in tone and nature.
On 17 April 1956, Plath sent a batch of poems for his consideration, mentioning that her poems have previously appeared in The Atlantic, Harper's, The Nation, Mademoiselle, and the New Orleans Poetry Journal. There are two letters to Henry Rago.
see page 434)
On 25 June 1958, Plath writes to Rago submitting a group of new poems written after a year spent largely teaching and not writing.
Another letter is addressed to the Copyright Department of Poetry and is dated 7 October 1961. In this letter she is asking, for Knopf, for copyright assignment to Plath for several poems that were to appear in Knopf's 1962 edition of The Colossus. The poems were "Metamorphosis" (since renamed "Faun"), "Sow", and "Strumpet Song".
Additionally, poets.org has an article "From the Archive: Sylvia Plath". At the bottom is a lovely slideshow of images of Plath related documents. No one I have written to at the Foundation seems to know where the original documents for slides 6-9 are. They were not among the photocopies I received of the Plath documents held in the papers at University of Chicago.
The digitized documents are Contributor Information sheets dated:
September 1956 (in conjunction with the magazines first acceptance of Plath's poems, which appeared in January 1957 ("Wreath for a Bridal", "Dream with Clam-Digger", "Strumpet Song", "Metamorphosis", "Two Sisters of Persephone", and "Epitaph for Fire and Flower");
20 September 1958 (likely for three poems --"On the Decline of Oracles", "The Death of Myth-Making", and "A Lesson in Vengeance" -- printed in September 1959);
9 November 1961 (for five poems --"Stars Over the Dordogne", "Widow", "Face Life", "Heavy Woman", and "Love Letter" -- printed in March 1962); and
29 January 1963 (for three poems --"Fever 103", "Purdah", and "Eavesdropper" -- printed in August 1963). This contributor information sheet (image 9 of the "From the Archive" slideshow linked just above) is one of the most absolutely tantalizing Plath documents I have ever seen. Why? She mentions that she was awarded a Saxton Grant for a novel which was published in England in 1963. But there is some blacked-out, redacted text. What was that text? In size, it is approximately the same 'shape' or length as THE COLOSSUS which is (with spaces) 12 characters long. Did she list the actual title of her novel: THE BELL JAR, which is (with spaces) also 12 characters long? But it does not look like the text is in all caps. Did it say something like "which has been" or "which was just", which is 15 and 14 characters respectively? And who redacted it? I want to know! The text that eventually appeared with her three poems, which Plath submitted to Poetry on 23 November 1962 (along with five other poems: "Nick and the Candlestick", "A Birthday Present", "The Detective", "The Courage of Quietness" (later "The Courage of Shutting-Up"), and Lesbos") reads as follows and makes no reference to the novel:
The death of SYLVIA PLATH on February 11 of this year was a shock and great sorrow to the world of poets here and in England. Her first book of poems, The Colossus, was published in America last year by Knopf and in England by Heinemann. She was born in Boston on October 27, 1932, and educated at Smith and at Newnham College, Cambridge, where she took an Honors B.A. We cherished her contributions to Poetry from her beginnings as a poet, and awarded her our Bess Hokin prize in 1957. She was married to the English poet Ted Hughes and had two children. She sent us the poems in the present issue shortly before her death. (p. 347)The Lilly Library holds Poetry's records from 1954-2002. There is some overlap, in terms of years, with what is held at Chicago, but based on a search of the papers conducted by the ace staff at the Lilly, there is no Plath "stuff" in the collection.
You can see more libraries that hold Plath materials on the Archival Materials page of my website for Sylvia Plath, A celebration, this is.
