9: This selection of supporting papers to accompany the
10: Programmer's Manual
11: reflects both continuity and
12: change in the
13: UNIX research system since the last such collection appeared
14: in the seventh edition a decade ago.
15: Three-fourths of the papers are completely new, and
16: many of the rest have been substantially
17: rewritten.
18: Most of the papers represent the work
19: of members of the center where the system
20: was born, Computing Science Research at AT&T Bell Laboratories.
21: Previous work of this center has become so widely known that
22: many of the more basic papers from the seventh edition
23: could safely be dropped to make way for more recent material.
24: .PP
25: Some papers continue important themes that date from
26: the early days of the system: software tools, program
27: development, text processing, document preparation.
28: Some address the down-to-earth subject of the
29: care, feeding, and protection of a multifaceted system
30: in an imperfect world.
31: Others address the increasingly pervasive
32: theme of communications and distributed
33: computing: `stream' connections among
34: processes and files on one or more computers,
35: cross-machine file systems,
36: multiplexed (windowed) terminals,
37: worldwide electronic mail.
38: A few papers suggest the breadth
39: of research applications that meet and reinforce each other
40: in this system: music, graphics, protocol verification,
41: image processing.

43: Here one can find more up-to-date information
44: about the popular
45: .I troff
46: family of typesetting software than
47: in any other published work.
48: One may also see, in the diverse styles of the several
49: authors, various ways to exploit
50: .I troff
51: and some of its newer rivals.
52: In the useful index by Lorinda Cherry and the playful
53: .I pico -portraits
54: by Gerard Holzmann, one may enjoy some unusual outputs from
55: .SM UNIX
56: tools.

58: Besides the authors of the individual papers, many other
59: people have helped to bring the tenth edition system into
60: being.
61: They are acknowledged in the preface to Volume 1.
62: The manual is dedicated to the memory of the late Lee McMahon, whose
63: influence pervades the system's approaches
64: to text processing and data networking.
