The North Carolina Literary Review put out a Black Mountain Issue in 1995. The Black Mountain Museum had copies on hand and I scooped one up. Around 150 pages of material on the College with interviews, poems, memoirs and articles. Looks promising, I'm not so hot on the rest of the issue but not everything can be pure gold like the Black Mountain Review, if you can dig one of those up. That said back issues of NCLR are still available for $15: http://www.nclr.ecu.edu/issues/back-issues.html.
