Not strictly a book, but this made something "click" for me back in the early days: http://sepwww.stanford.edu/sep/jon/family/jos/oop/oop1.htm http://sepwww.stanford.edu/sep/jon/family/jos/oop/oop1.htm Sadly the author passed away in 1999 -- when he was younger than I am now & just a few years after I first read his "book". IIRC his parents were still trying to get the book published for a while. Looks like his family maintains a web site in his memory: http://sepwww.stanford.edu/sep/jon/family/jos/ http://sepwww.stanford.edu/sep/jon/family/jos/
