When I was in semiconductor manufacturing, I kept a set of notes in LaTeX, with a different chapter for each process layer. I'd print these out and annotate in the margins. Whenever the margins filled up, I would transcribe my marginalia and print a new version. This strategy works best when you're in-office and somebody else is paying for paper and toner. It's not effective in the context I'm in, but it worked great at the time.
