This is the second 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 third, Digital Typography.) The Computer Science volume is characterized by the following remarks quoted from its preface.
This book assembles under one roof all of the things I've written about computer science for people who aren't necessarily specialists in the subjectfor scientists and mathematicians in general, and for educated people in all fields. I'm grateful for this opportunity to put the materials into a consistent format, and to correct errors in the original publications that have come to my attention. If any of this work deserves to be remembered, it is now in the form that I most wish people to remember it.It has the following chapters:
(Numbers like P79 and Q82 in this list refer to the corresponding papers in my list of publications. The chapters are numbered from 0 to 16; some buggy browsers unfortunately show them as 1 to 17 in the listing above. In the first two printings, Chapters 14 and 16 were called Chapters 15 and 14, respectively, and the new ``St. Petersburg'' chapter was not included.)
Available from the publisher (CSLI), and also from the distributor (University of Chicago Press).
It is a real pleasure to reread these articles, which are generally as fresh today as when they were first written. The Scientific American article entitled ``Algorithms,'' from 1977, ... is still the best treatment of searching that I have ever read.  J. Nunemacher, IEEE Annals of the History of Computing, 1998
This is a delightful book.  R. B. Kellogg, SIAM Review, 1998
Immensely satisfying.  S. Khuller, SIGACT News, 1998
It is a lovely read ... clear and crisp.  Adrian Larner, The Computer Journal, 1998
... Covering a period from 1966 to 1993, its interest lies not only in the content of each of these papers  still timely today  but also in their being put together so that ideas expressed at different times complement each other nicely.  N. Bernard, Zentralblatt Math
... This is a fascinating survey of the work of one of the most important computer scientists ever. In particular, his discussion of theory and practice and his view of algorithms and algorithmic research enhance this impressive survey of the development of computer science. His clear and entertaining way of writing makes it a pleasure to read the book.  F. Meyer auf der Heide, Mathematical Reviews, 1998

I hope the book is otherwise errorfree, but (sigh) it probably isn't. Please send suggested corrections to knuthbug@cs.stanford.edu, or send snail mail to Prof. D. Knuth, Computer Science Department, Gates Building 4B, Stanford University, Stanford, CA 943059045 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, and to pay your reward with interest compounded from the day you pointed out the error.
DO NOT SEND EMAIL TO KNUTHBUG 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 brandX operating systems for all values of X.
