A note from the editor of this edition....
"The title of the collection remains potentially misleading: an academically complete edition, which would contain all Bunting's fragments and variants, letter-poems, and poems of dubious ascription, must await another editor in an age when all the manuscript and typescript remains of Bunting have been docketed and indexed. As partial repayment of my own debt to Bunting, my task has been to maintain the shape of a book which is complete for readers of poetry".
Durham / August 1999
So it is really quite a stretch of the imagination to attack it for not being a 'complete' volume.
It has everything that a Bunting reader could want and only lacks those things from which academic pundits might fashion an article.
