Introducing *TeX: The Program*, the definitive source code and program listing for the groundbreaking typesetting system created by Donald E. Knuth. Celebrating over 35 years since the first edition, this volume reflects the culmination of meticulous review by the world’s leading experts on TeX. Every detail has been carefully examined, ensuring that "every 'i' has been properly dotted, every 't' has been properly crossed, and every bug has been properly exterminated."
Donald E. Knuth, renowned for his pioneering work in computer typesetting, provides in this volume the fully documented program listing for TeX. Readers familiar with TeX and its user’s guide, *The TeXbook*, will find much of interest within the source code itself. For those interested in software development or Knuth’s distinctive programming style, this serves as a fascinating and instructive case study. Never before has a program of this magnitude been presented with such clarity and completeness.
Knuth employs the WEB system of structured documentation—developed as part of his TeX research project—to present all algorithms and explain every detail of the TeX program. This comprehensive approach offers an unparalleled insight into the inner workings of one of the most influential typesetting systems ever created.
*TeX: The Program* is the second volume in a five-part series on Computers and Typesetting, authored by Knuth. This series encapsulates the results of nearly a decade of innovative research dedicated to solving the complex problems involved in producing high-quality publications.
