The History of Middle-Earth Index by J.R.R. Tolkien
My rating: 4 of 5 stars
This isn't so much a review as it is a recommendation. If you are interested in using The History of Middle-Earth as a source for studying Tolkien, this book is an indispensable aid. It's hard to come by, but will make for a lot less work. Not that flipping from volume to volume isn't fun.
