For those of you who like to keep things organized and have it categorized, I've made a nice handy chart that can help you out!
Pages coded in red mean they are not obtainable through normal gameplay.
Oil is coded in blue because I'm not entirely sure whether or not it is obtainable at all. (NOTE: Oil can be obtained!)
Anyway, I hope this chart serves great use to you in creating your world(s)!
