Harry Potter and the Prisoner of Azkaban

UK Bloomsbury is the true first, ahead of the US Scholastic edition (also 1999). The decisive first-state points are the 'Joanne Rowling' copyright credit, the page 7 dropped line, and the complete 10-to-1 number line. Bibliographer Philip Errington records about 5,150 first-impression copies, of which roughly 2,500 are first state.
