Nearly two years ago I posted about the methods I use for planning adventures and campaigns; here's a link to that post.
This post builds upon that one, sharing my version of what some people call the "campaign Bible." For me it comes in two forms, my campaign binder and my collected PDFs.
The campaign binder is pretty straightforward; it's a typical three-ring binder divided into sections for Resources, Scenarios, Conventions and Session Notes.
Because I'm writing for my blog, I also print the PDFs, three-hole punch them, and then use binder rings to collect them. This gives me a physical reference for sessions.
