[thelist] technical publishing, math formula

[Sam-I-Am]

I'm looking around for technical publishing resources  (print and web),
in particular using Quark - best practices, links, books, tools, tips,
services, etc.

Also (and in particular) handling math formula

I'm looking at the w3s MathML, and am digging into lots of Tex/LaTex
stuff. But this client is using Quark - any direct experience with this
kind of thing on the list?

thanks,
Sam
