This is the third in a series of eight volumes that contain archival forms of my published papers, together with new material. (The first book in the series was Literate Programming; the second was Selected Papers on Computer Science.) The Digital Typography volume is characterized by the following remarks quoted from its preface.
This book brings together more than 30 articles and notes that I have written about the subject of digital typography, popularly called “desktop publishing.” It was my privilege to be present at a time when a significant revolution was taking place in the way words, symbols, and images were being rendered in printed documents, as analog methods gave way to digital methods that are amenable to computer processing.
I guess I must have ink in my veins: When I first learned about the potential of digital printing technology, I couldn't resist putting the rest of my life on hold while I tried to adapt the typographic wisdom of previous centuries to the possibilities of the present day. I hope the reader will be able to share some of the excitement of my decades-long quest to produce beautiful books with the help of computers.
Leonardo da Vinci made a sweeping statement in his notebooks: “Let no one who is not a mathematician read my works.” In fact, he said it twice, so he probably meant it. But, thank goodness, a lot of people failed to heed his injunction; non-mathematicians are quite capable of dealing with mathematical concepts, when the description isn't beclouded with too much jargon. So I would like to reverse Leonardo's dictum and say, “Let everyone who is not a mathematician read my works.” (Furthermore, mathematicians are invited too.)
Every author likes to be read, of course; I've quoted Leonardo chiefly as a sort of apology for the fact that some chapters of this book were originally addressed to professional mathematicians, while others were addressed to graphic artists or to people from other disciplines. My hope is that by keeping jargon to a necessary minimum I can communicate some significant ideas that cut across many specialized fields. Indeed, the study of printing is probably as interdisciplinary as any subject can be.
It has lots of cool graphics and the following chapters:
(Numbers like P91 and Q69 in this list refer to the corresponding papers in my list of publications.)
This book first arrived at Stanford on February 18, 1999; then, its glorious second printing arrived on May 26, 2012. It can be ordered from the publisher (CSLI), and also from the distributor (University of Chicago Press).
This is an electrifying book. The essays collected here helped lead typography from its mechanical and photographic past into its electronic, digital future. ... In Knuth's illuminating vision, mathematical typography took its proper place in the history of ideas, not as a niche subject, but as a broad and richly fascinating field that deserved and invited deep investigation. ... In addition to their scientific content, these essays often reveal the personable, quizzical, and humorous characteristics of the man behind the mathematics, qualities which those of us who were privileged to work with him remember with fondness. -- Charles A. Bigelow (1998)
The author of the monumental The Art of Computer Programming has outdone himself with this remarkable book. It is not often that a book dealing with a dry, esoteric topic elicits adjectives such as engrossing, engaging, and illuminating. Knuth shows convincingly how mathematics is put to use to produce better typesetting tools and fonts, while improved typesetting produces a much more elegant display of intricate mathematical formulas.
Even though the book is primarily a collection of essays, speeches, scholarly papers, and user-group articles spanning two decades, it has a seamless air. Knuth explains why the quality of typesetting of mathematics declined drastically during this century, to the extent that he set aside his main mathematical efforts for over ten years to set about remedying the situation. He details why he created TeX, and why he found it necessary to create METAFONT as well. Parts of the book read like a good mystery, and parts really put your mathematical background to the test. This book is itself an exemplar of typesetting at its best. If readers are not acquainted with Knuth's other works, after reading this book they will become converts.
In the many years I have been reviewing for this publication, I think this is the first time I can say “This is an enjoyable book.” Many books I have reviewed were well written, informative and useful; this one is all of the above, and enjoyable. -- E.J. Desautels (Computing Reviews, September 1999, page 433)
I have found this book a wonderful source of both information and knowledge. Whether you're new to type or you've been using it for 20 years or more, there's something here you didn't know. Go and buy it now. -- Peter Flynn (TUGboat, December 1999, page 365)
... full of the qualities for which Knuth is famed: original analyses, careful and deeply researched scholarship, explications which show how much he wants people to understand what he has found out, and unusual but apt quotations and humor. ... There is an enormous amount of material in this book, and you don't have to be fascinated by all of it to find it attractive, although quite a few will be. Of course, the care shown in the book production is exemplary, and the price remarkably low for it. ... Knuth's work on digital typography has empowered both the scientists who use it to express their research and artists who have begun to use it elsewhere. -- Patrick Ion (Math Reviews, November 2002)
... He being a great writer, a dedicated typesetter and a rather meticulous font shaper, made this book an extreme pleasure to read. Every article, every page, contain interesting observations relevant to everybody who has ever been involved in writing books or articles.

- Addendum (December 2002)
In 1998, TeX became certifiably Y2K-safe by printing the current year with four digits instead of two.
A bug in \xleaders was found in 1999; some tricky ways to defeat TeX's alignments were defeated in 2001; the rounding of glue was improved in 2002.
But I remain optimistic that no further changes will be needed.
Addendum (March 2008)
Following a substantial analysis of the entire program by David Fuchs, eight more changes were made in TeX version 3.1415926---one each of Types B, F, I; two of Type E; and three of Type R. No major errors were found, but we wanted to make the program more robust and consistent. The most significant problem to be corrected was the fact that leaders with \mskip glue had never worked properly; that feature, which nobody could actually have used, is now disallowed. Further details about the changes, which bring the total number up to 946, appear in my note “The TeX tuneup of 2008,” TUGboat 29 (2008), 233--238.

I hope the book is otherwise error-free; but (sigh) it probably isn't, because each page presented me with hundreds of opportunities to make mistakes. Please send suggested corrections to knuth-bug@cs.stanford.edu, or send snail mail to Prof. D. Knuth, Computer Science Department, Gates Building 1B, Stanford University, Stanford, CA 94305-9015 USA. In either case please include your postal address, so that I can mail an official certificate of deposit as a token of thanks for any improvements to which you have contributed.
I may not be able to read your message until many months have gone by, because I'm working intensively on The Art of Computer Programming. However, I promise to reply in due time.
DO NOT SEND EMAIL TO KNUTH-BUG EXCEPT TO REPORT ERRORS IN BOOKS! And if you do report an error via email, please do not include attachments of any kind; your message should be readable on brand-X operating systems for all values of X.
