Notes: Data except ISBN from Amazon UK 2022-07-11 as "Kindle Edition" and "Kindle Price: £2.99 ... This price was set by the publisher." "Look inside" shows that a different map precedes each of the Prologue, Chapter I, and Chapter II. Those are three among "Chart One" to "Chart Sixteen" listed in the Contents. Hume acknowledges "the artists, designers and cartographers" (none named); "... they take my maps and charts and drawings and, and turn them into a common-sense presentation that encourages the reader to buy my books." British Library (BL, below) states:   ISBN 9781472215765 (ebook) : £19.99 That price is incredible and probably belongs to the simultaneous 1st ed. hardcover.
