I'm compiling sources pertaining to Nationalist era society, in the US. I have serious history, like
The Guns of August and
Over There, but I need info on the superstitions and fringe worldviews, expressed in science, religion, politics, and technology. I need contemporary sources on the occult fiction, extraterrestrial life, and hidden, zany history. Stuff like space flight in blimps, and moon men. Sources of contemporary vernacular would be appreciated. I'm having a hard time knowing where to begin searching.
