This book is a decent reference. I include it here because Latex has been around for a long time and I find it useful for doing stuff like generating pdf reports via scripts, or even typing up notes for work, or other everyday uses.Latex allows you to focus on content and not on layout. For a guy like me that is a really nice thing. I don’t have to worry about what it’s going to look like because I know that latex will make it look nice.
If you are interested in latex you may also want to lookup Lyx and Xetex Lyx is an editor which helps you with the markup, and Xetex uses pretty much the same syntax as Latex, but adds extensions to allow you to use Unicode and modern fonts such as OpenType fonts.
