Volume I came out in May 1834. Lord Mahon dined at Apsley House on 18 May and reported that the Duke was much amused at reading it: 'the energy and activity are quite as great then as afterwards. I don't think that I could write better now, after all my experience.' Volumes II and III came out in March 1835. Volume III was a supplementary volume containing papers that had come to light since the first two were prepared. Indeed there was so much new material that Gurwood considered producing a second edition with the documents in their correct date order and running to a fourth volume. The booksellers were pressing for a reprint as the first edition was sold out. He decided in the end to issue three new volumes with all the papers, including much new material, placed in date order. His explanatory notes were excised, and the contents consisted only of letters written by the Duke with a few letters written to the Duke retained as (sometimes lengthy) footnotes. Volumes I - 3 of the New Edition were published in 1837.
