Market value

What decides the price

  • It is the first edition, which is the one collectors want.
  • The original dust jacket carries much of the price for a book of this age; its condition matters as much as the book's.
  • Condition is graded separately for book and jacket, from Fine down to Poor.

Identification

How to identify this edition

Published in London by George Allen & Unwin in 1959; Simon and Schuster issued an American edition in New York the same year, so check for the London imprint. The British hardback has 279 pages, 23 cm, and ends with an appendix, Russell's Philosophy, by Alan Wood. The book predates ISBNs, so the number 0 04 192015 5 attached to some catalogue records cannot appear in a 1959 printing. A second impression is also dated 1959, so check the reverse of the title page for an impression statement. The Unwin Books paperback of 1975 and the Routledge (1993, 1995) and Spokesman (2007) editions are later.

Publisher's practice

How Allen & Unwin marked its first editions

  • First-impression jackets of The Hobbit (1937) carry a hand correction on the rear flap, where the misspelling "Dodgeson" (for Dodgson, Lewis Carroll's real name) was amended in ink by the publishers.
