"Look down at the bottom of the text of the day, where footnotes will explain all." So advises the narrator of Gravity's Rainbow (V204, B238), who later mocks our inclination towards endless pedantic emendation of those same "footnotes." Never mind the mockery; numerous references in the novel show that Pynchon himself is a close reader of scholarly annotations. For other emendators, here then are some corrections/additions to David Seed's "Further Notes and Sources for Gravity's Rainbow" (PNotes, 16 [Spring 1985], 25-36), a quite useful addition to the textual study of the novel. Page references are to the Viking (1973) and Bantam (1974) editions.
