William Gaddis’s cut-and-paste notes toward composing his novel J R. Check out more of Gaddis’s notes for J R at the Modern Literature Collection at Washington University. (They also have a really cool new YouTube channel).
Gaddis’s cut-and-paste technique evinces in J R, particularly in the authorial stand-in Jack Gibbs, who muddles about with scraps of ideas in his pockets—scraps that perhaps eventually become (a version of) Gaddis’s last novel Agapē Agape.
I wrote about Agapē Agape here and a recent rereading of J R here.
