Here's Sam's explanation:
Nomenclature books are pretty much books that you identify what color the covers are supposed to be by the rim of the book that you're copying from. Blue stands for geography, and red stands for zoology, and green stands for botany, black stands for geometry, and yellow stands for history.Did that explanation clear it up for you? Oh well, at least it was an amusing little discourse on nomenclature books.
I do nomenclature books cause they're not too hard, but good work. There's a picture on one page and a sentence on the other. Each page describes a part of what you're writing about in the nomenclature book. Drawing the pictures isn't too hard depending on what the book is.
Here's my favorite book so far: Fundamental need of Humans: Defense. Just check out the cover illustrations of military technology through the ages - inspirational! I'm not totally sure what the flying tongue there under "Defense" is supposed to be, but I'm inspired nonetheless. My child will soon surpass me in artistic ability.
This is my favorite page from Fundamental need of Humans: Defense. It reads: perhaps the most important of the ancient greek weapons was the hoplite or foot soldier. No, I'm not totally sure what that means, either, but it's got a killer (heh heh, get it? killer?) illustration. Great work, Sam!
