The Lions Book
Since source code was available and the license was not explicit enough to forbid it, V6 was taken up as a teaching tool, notably by the University of California, Berkeley, Johns Hopkins University and the University of New South Wales (UNSW). Berkeley distributed a set of add-on program called the First Berkeley Software Distribution or 1BSD, which later became a full-fledged operating system. UNSW professor John Lions' famous Commentary on UNIX 6th Edition was an edited selection of the main parts of the kernel as implemented for a Digital PDP-11/40, and was the main source of kernel documentation for many early Unix developers. Due to license restrictions on later Unix versions, the book was mainly distributed by samizdat photo-copying.

Famous quotes containing the words lions and/or book:
“Sure, you can love your child when he or she has just brought home a report card with straight “A’s.” It’s a lot harder, though, to show the same love when teachers call you from school to tell you that your child hasn’t handed in any homework since the beginning of the term.”
—The Lions Clubs International and the Quest Nation. The Surprising Years, II, ch.3 (1985)
“When we read a story, we inhabit it. The covers of the book are like a roof and four walls. What is to happen next will take place within the four walls of the story. And this is possible because the story’s voice makes everything its own.”
—John Berger (b. 1926)
