The Second World War (6 vols)

Confirms the census. The Houghton Mifflin (Boston) edition precedes the Cassell (London) edition throughout the series: The Gathering Storm was published in the US on 21 June 1948 against a British October 1948 issue, and the sequence holds to the end — Triumph and Tragedy appeared in the US in November 1953 and in Britain in April 1954. The US set is therefore the true first edition, first printing. Both sets are collected, and the census note on text is sound: the Cassell London volumes were issued within months of the American and incorporate numerous corrections and a few additional maps, so the UK set carries the better text while the US set holds precedence. Name both when cataloguing.
