It’s also characteristic of K&R that they have this statement on the copyright page:
This book was typeset (pic|tbl|eqn|troff -ms) in Times Roman and Courier by the authors, using an Autologic APS-5 phototypesetter and a DEC VAX 8550 running the 9th Edition of the UNIX(R) operating system.
That they did their own typesetting is not just a cute touch, but an insight on the completeness of their mastery of what they were doing, and the care they took over it. The book is not what you would call beautiful to look at, but the typesetting is wholly functional, at one with the text rather than fighting against it. (Also, this statement is a gentle indirect boast, as Kernighan wrote the pic program and co-wrote eqn with Lorinda Cherry.)"
