The Complete Guide to Middle-Earth

The structure makes it so easy to find details, but I wonder if it was a challenge to decide what to include or omit in such a comprehensive guide.

Some of the definitions and cross-references added new layers to my understanding of Tolkien's world. Were there entries that changed how you viewed Middle-earth?

It’s incredibly detailed, but I’m curious how it stacks up against other scholarly or fan-made encyclopedias—what makes this one stand out?
