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:
“There is no magic decoding ring that will help us read our young adolescent’s feelings. Rather, what we need to do is hold out our antennae in the hope that we’ll pick up the right signals.”
—The Lions Clubs International and the Quest Nation. The Surprising Years, III, ch.4 (1985)
“If any ambitious man have a fancy to revolutionize, at one effort, the universal world of human thought, human opinion, and human sentiment, the opportunity is his own—the road to immortal renown lies straight, open, and unencumbered before him. All that he has to do is to write and publish a very little book. Its title should be simple—a few plain words—”My Heart Laid Bare.” But—this little book must be true to its title.”
—Edgar Allan Poe (1809–1845)
