SCO UNIX in a Nutshell Here are the changes from the 1/98 reprint: (i): removed the referees (iii): removed these referees too (569): changed the section about the refs to info about the bear (contact me and I'll send you the new text), and added the following to the last paragraph: Whenever possible, our books use RepKover (tm), a durable and flexible lay-flat binding. If the page count exceeds RepKover's limit, perfect binding is used.
