<P> The sinister fact about literary censorship in England is that it is largely voluntary...Things are kept right out of the British press, not because the Government intervenes but because of a general tacit agreement that' it wouldn't do' to mention that particular fact . </P> <P> Although the first edition allowed space for the preface, it was not included, and as of June 2009 most editions of the book have not included it . </P> <P> Secker and Warburg published the first edition of Animal Farm in 1945 without an introduction . However, the publisher had provided space for a preface in the author's proof composited from the manuscript . For reasons unknown, no preface was supplied, and the page numbers had to be renumbered at the last minute . </P> <P> In 1972, Ian Angus found the original typescript titled "The Freedom of the Press", and Bernard Crick published it, together with his own introduction, in The Times Literary Supplement on 15 September 1972 as "How the essay came to be written". Orwell's essay criticised British self - censorship by the press, specifically the suppression of unflattering descriptions of Stalin and the Soviet government . The same essay also appeared in the Italian 1976 edition of Animal Farm with another introduction by Crick, claiming to be the first edition with the preface . Other publishers were still declining to publish it . </P>
