Forty is too few 

Whoever changed the number of books written from 50 to 40 - that number is way too low. I count well over 50, and this is only counting the primary publications, and only books with more than one story or poem (Black Sparrow issued books at the end of each year containing one story or anywhere from one to six or seven poems). Yes, it's a lot. But it's not an inflated number (Krumhansl's "A Descriptive Bibliography of the Primary Publications of Charles Bukowski" lists over 70 books), so let it stand.
