The series was projected for 17 titles, of which ten were published during 1941-42, but bomb damage to Warburg's office and the destruction of his printer's paper stock led to the series being discontinued.
The first in the series, The Lion and the Unicorn, was published on 19 February 1941 with an initial run of 5,000 copies, but the number was raised to 7,500. A second printing of 5,000 copies was ordered in March 1941. It sold over 10,000 copies (and was among the most commercially successful of Orwell's books to that date). The destruction of the stock by bombs ended its sales.
