This book is amazing; the fact that she was able to work out most everything involving geology just from Tolkien's descriptions is wonderful.

> I have a book of maps for his world on a bookshelf here which I got when I was young (The Atlas of Middle-Earth)

This atlas is fantastic. An absolute must-have.

There is a new edition in French with redrawn maps that are great. I did not triple-check everything but as far as I can see they are just like the old maps in terms of details and accuracy, only much more beautiful. There are some pictures here: https://www.artstation.com/artwork/03b6ZK .

I have no idea if these maps will be published in English, AFAICT this cas commissioned specifically for the new French edition.

(I had thought I had seen a higher-resolution version, but not finding it now)

I have that same book. It was a major source of inspiration when I was a kid.
