THAT DAVID COPPERFIELD KIND OF CRAP

Dickens' style is distinguished from other authors for his fastidious writing and acute attention to detail. Dickens loves to go into every minute detail about a character to animate them to life for the reader. When Holden says he does want to go into "all that David Copperfield kind of crap" he saying he doesn't want to go into the intense detail Dickens usually does. Salinger probably respects Charles Dickens as a writer but chooses to refer his attention to detail as "crap" because it provides his audience with some characterization of Holden. By distancing his protagonist from Dickens', Salinger can juxtapose the characters and their writing styles.
