Door into the Dark
Seamus Heaney · Faber & Faber, London · 1969
Faber & Faber (London), 1969 is the true first, confirming the census claim; the Oxford University Press (New York) 1969 issue is the first American edition and follows it. Both are collected. The two are easily confused because the American issue is described in the same black cloth with gilt spine lettering and the same red/green/white jacket, so the title-page and copyright-page imprint is the only safe check. A frequently repeated claim that the OUP issue was made up from purchased Faber sheets could not be corroborated and should not be published as a point.
