Allen and Unwin. all 1967 2nd edition, 2nd printing. 1966 was the first printing of the second edition, but they failed to make all the correction. Professor Tolkien insisted they re-print them immediately. They had to produce a second edition (new edition) in the first place following the copyright disputes over the ACE editions. Thereafter we see all the key text changes and it remain as we see them today other than correction of typoes. Both the first and second printings are must-haves for any collection. They later printings were just re-prints and not as important as far as content corrections. Note, the second printings do not have the correction tot he title errors on the jacket flaps, one of the ways to identify a true 1966 set. This is an exception set with very little chipping to jackets. Some crease lines and minor chipping to spine ends. The spine titles are clear and white, often slightly faded to off-white. Books are read several times but no serious flaws. They have the owners name to each end pages indicating a beloved set kept together. The overall condition is the most important factor to the value. As good as set as you'll find as the early second editions are now very scarce.
