Camp Concentration

The UK Rupert Hart-Davis edition of 1968 is the true first book edition and precedes the US first (Doubleday, Garden City, New York, 1969) by a year — the census claim is correct and is confirmed independently by L.W. Currey and Burnside Rare Books. Both editions are collected, the Hart-Davis as the true first and the Doubleday as the first American. Note the genuine first appearance of the text is serial, not book: Camp Concentration ran as a four-part serial in New Worlds, July–October 1967, under Michael Moorcock's editorship, so the magazine appearance precedes both book editions.
