I've been reading The Elements of Typographic Style and I was wondering whether there was a similar resource for specifically mathematical typesetting.
Is there a book or other document that sets out answers to the following questions: - What are the basic units of mathematical writing and how much space should there be between each of them? - What fonts are available that contain a good selection of specially designed mathematical symbols (Sum and integral symbols; Greek letters that fit with the italic and roman alphabets; arrows, primes, etc. that fit with the typeface) - Advice on when inline maths is appropriate and when formulae should be on a new line.
Ideally something that deals with these questions with an eye to TeX and friends, but I'm really looking for something on typography. N.B. I'm not really looking for answers to the above questions here, but for resources that offer answers to them as part of a systematic treatment of mathematical typesetting in the mould of Bringhurst's Elements …
