Provides an example-based, visual approach and a gentle introduction with the Short Course. This is a detailed exposition of multiline math formulas with a Visual Guide. It offers a unified approach to Tex, Latex, and the AMS enhancements. It also provides an introduction to creating presentations with computer projections.
Quite comprehensive review up to 2007 of the evolving LaTeX system. I would have liked better to distinguish all the various packages instead of lumping them all together into "LaTeX", but it is certainly true that most distributions simply install them all, so the difference is for the control freaks who want to know where everything is coming from. I do hope that LaTeX3 finally arrives to organize the new 'core' LaTeX so that we don't have to think in terms of packages any more, nor in terms of different implementations achieving the same effect.
There was no ention of the microtype package in this book... perhaps it was too new when it was written (6 years ago now). There was also very little mention of XeTeX or LuaTeX, both of which projects seem to have some steam behind them. In particular, XeTeX could finally solve the problem that TeX has always had: mainstream fonts. Of course, if one is typesetting math, one might need specialized (and not mainstream) fonts. Still, it would be quite convenient to install fonts in the operating system, and without doing anything further, having those fonts readily available to TeX.
This book is published in the US under the name More Math Into LaTeX, 4th Ed. This is by far the most comprehensive book I have seen for showing how to create mathematical expressions in LaTeX.
