At 730 pages, with dense maths, extensive cross-referencing, multiple bibliographies, index, etc. this book:
cambridge.org/9780521108065 is the best recent example of an engineering/science book in *roff, that I know of. >From the preface: "Except for Chapter 9, I have formatted the book using ditroff. Most of the figures and the graphs are constructed by pic and grap. In this connection, I wish to thank Frank Dwyer who helped me to move old ditroff editing and formatting tools from an old Sun system to a new one, which allowed me to continue to use many macros that were constructed particularly to tailor the figures and equations to my taste. Chapter 9 was formatted using grof, and I wish to thank my graduate student Mr. Sai Sarva who helped to solve a number of formatting problems, thereby rendering this chapter consistent with the rest of the book." If he can do it so well, it's certainly a motivation for me to invest some time in learning groff and related tools. Anton
