This book claims to be based on the “New Revised Edition of Conan’s Complete Works” (Tokyo Sogensha, 2006-13)” and is completely revised by translator Nakamura Toru.

It’s mostly just a re-issue of the six volumes series that came out in 2009. Probably an updated version where the translator fixed some earlier mistakes and whose translation is a hybrid between an already existing translation and the text of the Wandering Star editions. As the majority of the “edits” found in the Wandering Star/DelRey editions are commas or colons, this doesn’t affect the translation at all).
