The galleys print "A.F.R.aid" twice for "afraid" in Dolores's p. 765 passage — an error with "obvious allusive frisson" corrected away for the hardcover.
This is a revision: the same material was reworked in substance between draft and print.
In the galley proofs. The 1995 galley proofs reads A.F.R.aid at both spots — "persons who are deeply A.F.R.aid … of their own emotions," "…A.F.R.aid … of obliteration, emotional engulfment" (print: plain "afraid"; "A.F.R.aid" occurs nowhere in the digest text).
In the published book. Scene 154 (pp. 755–769; the p. 765 site)
Evidence. A single source reports this. Documented by the DFW Words galley-versus-first-printing collation — "This is a very unusual error, probably a completely random typescript mistake (was there a search and replace "afr" with "A.F.R."?) but it has obvious allusive frisson".
Bears on. This difference bears on the following open questions: intentional-errors.
Further notes. The direction surprises intuition — the frisson reading was in the GALLEYS and was corrected AWAY. Evidentially useful as a documented case of an accidental-looking-meaningful variant that the production process removed: a caution datum for intentional-errors arguments that treat surviving oddities as design. Re-confirmed from the acquired blog HTML: A.F.R.aid is in red (galley-only) and "afraid" struck through (hardcover-only) at both sites — the decode direction stands on the markup itself.
