For modern / near future: gun /outdoor magazines of all kinds work for me.
For FRP: historical and metaphysical magazines (for info on magical concepts).
I'd have to say Parabola Magazine. It's a quarterly. Each issue is devoted to a single theme that is addressed by myth, religion, and philosophy, such as the Hero, War, or Death, and presents a mind-bogglingly diverse anthology of writings and artwork on that theme from all cultures and historical eras.
