Computers and Typesetting is a 5-volume set of books by Donald Knuth published in 1986 describing the TeX and Metafont systems for digital typography.

In the series of five books Knuth not only describes the TeX and Metafont languages (volumes A and C), he also describes and documents the source code (in the WEB programming language) of the TeX and Metafont interpreters (volumes B and D), and the source code for the Computer Modern fonts used by TeX (volume E).

The book set stands as a tour de force demonstration of literate programming.

The books themselves were typeset in the Computer Modern Roman typeface using TeX; thus, in Knuth's words, they "belong to the class of sets of books that describe precisely their own appearance".

A jubilee edition of the Volumes A to D was published by Addison-Wesley in February 2021, incorporating all the changes made during the TeX tune-up of 2021.
