I recently re-skimmed Camp Concentration by Thomas M. Disch to list the words he uses that I did not know. In this list I do not include words he uses and then immediately defines (e.g., orthoepy), or obscure words I already knew (e.g., supererogatory), or words I believed to be proper nouns. I mark with an asterisk words that are nearly defined in the text and words I was nearly sure I already knew. Where the word appeared at the beginning of a sentence and I'm not sure whether it's a proper noun, or derived from one, I've preserved the initial capital letter. Here they are, in the order they appear in the book:

Pellucidar, empyrean, hermetic*, triturated, factoricity, tappets, lutulence, caliginous, resile, chrism, Hierodule, hypogeum, breccia, spirochete*, treponeme, orchitis, tabes dorsalis, Adamite, chilead, megrims, scherzoes, quaggy, unhouseled, fire-drakes, squitters, jactitations, hassock, enfouldered, stabile, quittors, oblate, athanor*, electuary, telluric, minorating, perfervid, concinnate, factoricity, ortilans, sacerdotal, philoprogenitiveness, ruck, hypogeal, daedal, fane, cornua, epalpibrate, picador, pic, banderilleros, hierograms, catechesis, symbolatrous, cope (noun), drier (noun), benisons, tellurian, bellycrabs, viscid, Carmot, crozier, hyperdulia, opuscula, crapulence, stelae, chiliasts, glouting, epithesis, illapses, wyverns, virescense, latria, umbelliferous, plash, fascinariorum, Ramiform, conatus, Anastomosis, haecceity, farctate, flagitious, squiffy, satispaison, rugate, cerebration*, emulous, gravid, compassionating, spining, sybilline, moiety*, perforce*, bolking, innocuity*

I have not looked up any of those words yet, as I am posting this partly to suggest Camp Concentration as a word source to the officiants of my neighborhood vocabulary bee. Also, I used my phone to note down the words I found, so a side benefit is that my autocorrect just got a lot more highbrow.
