RPG Ramblings Guide to Book Layout - Initial Research

Before starting a project, take a critical look at existing products. How are they laid out, what critical choices did they make, and what elements fit the tone and feel for your project?
This is a short survey of a sample of RPG products with my commentary.
Books Surveyed:
Journal to the Travellers Aid Society
Traveller
Star Frontiers
Fate Core
Cypher System
Star Wars: Edge of the Empire.
