General ⇒ Operating Principles of the (La)TeX Compiler

[CoolnessItself]

For me, LaTeX is a black box in the middle of my TeX and the first output stage (DVI, for example). I find very little information about the behind-the-scenes TeX interpretation/compilation. Is there a resource for how this works in general?

[Stefan Kottwitz]

It depends on how deeply you would like to understand the compiling process. LaTeX is just a format, so you should look for TeX. You could read the TeXbook, or the TeX82 description.
