This is not a review of the Elric stories (which are excellent). Rather, it is a brief commentary on Del Rey's slapdash organization of the material. In their six volume series, Del Rey published the stories out of order. Furthermore, the collection is incomplete. They left out a lot of material.

I recommend tracking down the Orion/Gollancz UK publications from 2013/2014. They published all of the stories in seven volumes and in order.
