hans aberg asks,
In the past, it was mentioned literature describing (traditional)
typesetting rules of mathematics. But unfortunately, I did not copy those
references, and from time to time, I encounter people who want to know.
Could somebody be kind and indicate some references to such literature
attached is the list i send out whan anyone asks.
i also know about an issue of the Monotype Recorder
that has an article by Arthur Phillips on the subject,
but since i haven't yet been able to get my hands on
a copy, it's not included here.
These four books are entirely about the composition of mathematics:
T.W. Chaundy, P.R. Barrett and Charles Batey
The Printing of Mathematics
Oxford University Press, London, 1954 (third impression, 1965)
Rules for Type-setting Mathematics
Publishing House of the Czechoslovak Academy of Sciences, Prague, 1965
Mathematics into Type
American Mathematical Society, Providence, RI, 1971, revised 1979
updated 1999 by Arlene O'Sean and Antoinette Schleyer
The original edition is based on "traditional" composition
(Monotype and "cold type", i.e. Varityper and Selectric Composer);
the 1979 edition adds material for computer composition, and the
1999 edition mostly assumes TeX or a comparably advanced system.
Mathematics in Type
The William Byrd Press, Richmond, VA, 1954
The following books contain material on mathematical composition,
but it is not the principal topic covered:
The Maple Press Company Style Book
York, PA, 1931 (reprinted 1942)
contains sections on fractions; mathematical signs; simple equations;
alignment of equations; braces, brackets and parentheses; integrals,
sigmas and infinities; hyphens, dashes and minus signs; superiors
and inferiors; ...
A Manual of Style, Twelfth Edition, Revised
The University of Chicago Press, Chicago, 1969
A chapter "Mathematics in Type" was produced using the Penta
The TeXbook is the manual for Donald Knuth's TeX composition system:
Donald E. Knuth
Addison-Wesley, Reading, MA, 1984
Appendix G describes the somewhat idiosyncratic mechanism used by
TeX to accomplish the composition of mathematical notation; it is
based on the principles laid out in the first three books above,
as well as on examination of a large number of published samples
that demonstrated Knuth's style preferences.
All but the Swanson, Knuth, and Chicago are out of print, but can
probably be found through a bookseller specializing in typography
