Anyway, I've long romanticized the books I used, but they disappeared (either I sold them back or I was sharing them with someone or several someones). So ... ten? twelve? years later, I finally tracked them down. Expensive as hell, but I want them again (and the time to read them, and apply them, and understand them better than I did back then...)
They were very mathy books (statistics).
