With the arrival of my lettered, limited edition copy of Only Forward this morning, I think I may have achieved a new goal; ten or more different versions of a book in English language editions only, not counting the translated versions.
(Original UK paperback. Reissued UK paperback. Re-reissued UK paperback. US paperback. SFBC edition. Proof for original UK paperback. Proof for US paperback edition. Proof for limited edition. Limited edition, numbered copy. Limited edition, lettered copy in slipcase. Yep - ten.)
I'm sure this proves something, but I'm not quite certain what. :)
