Rudy Rucker has A Writer’s Toolkit at his SJSU faculty Web site. The PDF file contains his “working notes for teaching writing workshops.”
Also on his site are his Writings About Writing, including essays on transrealism and the book-specific notes he made while writing his books. The “notes” for a given book can be anywhere from 14K (for THE HACKER AND THE ANTS) up to 100K words (for MATHEMATICIANS IN LOVE). An interesting look into how one writer writes.
