Collect all Journal notes in the game.
This would be hard - except for the guide books you can (and should!) buy in the three hub areas. Buy those and the locations will show up on your map. Make sure to pick them up as you play through naturally, and just fast-travel back later for any you've missed. You should pick up Field Survey for the first 50, and then this one when you've got all 100.
No checklist needed as the game keeps track for you and shows you where they all are.
