Donald Knuth's influence in computer science ranges from the invention of literate programming to the development of the TeX programming language. One of the foremost figures in the field of mathematical sciences, Knuth has written papers which stand as milestones of development over a wide range of topics. In this collection, the second in the series, Knuth explores the relationship between computers and typography. The present volume, in the words of the author, is the legacy of all the work he has done on typography. When type designers, punch cutters, typographers, book historians, and scholars visited the University while Knuth was working in this field, it gave to Stanford what some consider to be its golden age of digital typography. By the author's own admission, the present work is one of the most difficult books that he has prepared. This is truly a work that only Knuth could have produced.
