I have just received the following two notes about the upcoming book about Kay Nielsen.
Ole Damgaard says:
[The Kay Nielsen book is not out yet, but will be available in english via an american publisher. The danish version can be ordered directly from Vandkunsten, but I am guessing that you mainly would be interested in the english version. Will notify you when I know more.]
And Hans Perk adds:
[On Jan. 31st. I asked the folks at the Danish publishers, and got as answer "the publication of the Nielsen book is scheduled for the second quarter of 2008."]
