Let's say you learn absolutely nothing new in this small collection. So if you read the volumes closely, the interest is very limited. Indeed I expected to find key readings on the symbolic explanations of some passages, comments on the character to capture a little bit better their config. psychological, or more detailed insights related to places, but not, there is a pure and simple repetition of elements already mentioned in the novels galore. Hence some disappointment. I think it's mostly a marketing coup for King profitable franchise. To reserve for the ultimate fans and collectors to complete their Library. :)
