The Gygax's 75 Challenge by Ray Otus to give a very quick and easy system to build my own campaign in a very short amount of time
5. A copy of Johnn Four's '3-line NPCs' newsletter for most of my NPCs (I'd love to find the pdf of just the three-line stuff, so I have to make do with the newsletter)
6. A copy of the '7-Sentence NPC' article by C.M. Cline from Dragon Magazine #184 for my important NPCs
7. A copy of one of How to RPG's Adventure Locations by Fred Wheeler to use as a template for my own adventure locations to remind me that I don't have to overproduce to create a good adventure.
8. A copy of
B/X Options: Class Builder by Erin D. Smale to systematically create new classes to adjust the style or feel for any mini campaign
9. A copy of Johnn Four's '5-room Dungeons' article/newsletter to remind me how little one may need to create a quick yet intersting adventure location
10. AD&D 2e

Monstous Compendium to populate my settings with monsters. I like this book the most because it generally gives a great idea on how to fit the monsters in a campaign setting.
#2 through #9 printed out and put in a Pressboard two-prong Report Folder. I tried using a binder with rings for some of these, but turning pages started to suck. I think that's it for what I'd love to keep.
I have all of these printed out individually, but now that I've typed this up, I think I may just go and create my gotta have kit right now.
Edit: Fixed formatting and added comment about Johnn Four's '3-Line NPC' newsletter, added Johnn Four's '5-Room Dungeon' artticle, and added 2e
