Except for the McMaster University Library site on the internet that lists the date of publication as 1965 as in the Sackner copy, about five University Libraries list the date of publication as 1967. Thus, is the Sackner copy a first edition and the 1967 publication a second editions or is this a bibliographic error? The Sackner copy is not dated - the date is provided by Sharkey's holographic signature. Except for the title page, this poem is reprinted in its entirety in The Review of Contemporary Fiction Vol.7 No.2, 1987.It should also be noted that a 'proof copy' was printed in The Times Literary Supplement Thursday August 6 1964 and the Sackner Archive holds two copies of this publikcation. On fact. the final page of this book reads 'six poems from this sequence first appeared in the times lierary supplement.' -- Source of annotation: Marvin or Ruth Sackner.
