The twenty-fifth novel in the Discworld Series

 UK hbk: Doubleday, 2 November 2000 (0-385-60102-6)
Book proof: 370 copies released in June, of which 200 were signed by Terry for special presentation purposes – to mark the appearance of the 25th Discworld novel – unsigned copies are therefore the marginally rarer items.
The spine blocking on the first of the first printings (intended only for export to the Antipodes and South Africa), has a different typeface, similar to that used on exported printings of The Fifth Elephant, and to that on the ‘first’ edition sold in the UK, which is closer to the artwork on the dustjacket. As with The Fifth Elephant, this was not deliberate policy, merely a later refinement in the design.
Somehow copies were also sent out to Eymundsson in Iceland in August, and were immediately released to local booksellers and put on sale, to be pounced on with glee by local fans. The date for Transworld’s release of copies to ‘the Rest of the World’ was mid-September, while the on-sale date airside and internationally was 1st October. (In Britain the publication date is unaffected by overseas release dates.)
