non factual books are best as you can re-read them. my penguin paperback history of the USA (excellent) could keep me occupied for a week or a minute. when it eventuallly fell apart, it was a blessing in disguise. i scattered clips with 50 to 100 pages around bags and pockets so i've always something to read. started reduced copying other books (use the booklet option on the copier).
