Novel by
Nicholson Baker -- the entire text occurs during the main character's ride up an
escalator, following his
stream-of-consciousness and the generated
sub-references.
followup due to Gritchka's WU: I guess I misused stream-of-consciousness in its technical meaning. I intended it to mean what the character was thinking about, and the
train of thought, all the
minutiae and little stories. That's how most people think, I think. But maybe I'm just weird.
And I am about 90% sure that the
narrative starts just as he approaches the
escalator, and finishes as he gets off (though I remember that it snakes back to some previous details just to fill in
plot).
