In a comment to
the previous post on Emily Dickinson, I was asked if I preferred the version I posted of the poem which begins "Low at my problem bending" to a version which is available at
Bartleby.com (another great site), and if I have a book which explains why there are various versions of some poems.
I do prefer the version I posted, which comes from
this book, edited by Thomas H. Johnson. Though it contains all 1775 of Dickinson's poems, it is, according to the introduction, a condensed version of the 1955 3-volume variorum edition of The Poems of Emily Dickinson (also edited by Johnson — I've never laid eyes on it) which contained all extant versions of her poems as well as fragments.
According to the introduction to The Complete Poems, there seem to be various reasons for the existence of various versions of poems. One reason is that when Emily's sister Lavinia found 900 poems of Emily's in a box after her death and persuaded some folks to select and transcribe some of the poems for publication there was some apprehension about the public's willingness to accept the poems in their full eccentricity in 1890.
So a man named Thomas Wentworth Higginson, who had corresponded with Emily for years, often about poetry, "undertook to smooth rhymes, regularize the meter, delete provincialisms, and substitute 'sensible' metaphors. Thus 'folks' became 'those,' 'heft' became 'weight,' and occasionally line arrangement was altered¹."
Today, I suppose, most of us would see that as an incredibly arrogant and heavyhanded approach to preparing someone else's poetry for publication. Yet we also should note that in doing so Higginson honed the thin end (a volume of 115 poems) of what we now might think of as the wide, wide wedge of Dickinson which is firmly, perfectly, and thankfully driven between the increasingly insipid Romantic-style poets of the late 19th-century and those we conveniently lump together as the Modern poets (and their strange descendants) beginning probably with H.D., Pound, etc., in the very early 20th-century.
Another reason for the existence of various versions of Dickinson's poems is that she had never formally made final copies for publication: "several [versions of some poems] exist in semifinal form: those for which marginally the poet suggested an alternate reading for one word or more. In order to keep editorial construction to a bare minimum, I have followed the policy of adopting such suggestions only when they are underlined, presumably Emily Dickinson's method of indicating her own preference²."
