The Nature of Middle-Earth by J.R.R. Tolkien

This is a tough book to rate or review. This is a collection of notes made by Tolkien about everything from the gestational period of elves to making lembas. Included with each note is a description of the type of writing implement used and what kind of paper it was written on. (Tolkien used the blank backs of a variety of papers for a lot of these.) Some parts, like the math about the aging of the elves, are pretty dull, but I found myself drawn into the incredible details of the specifics of the elves' immortality and linguistics. This is definitely for hardcore fans only, but if you are interested at all in the minutia of Tolkien's impressive world-building, you should probably check this out.
