Herbert Voss is well-known as a maintainer of PsTricks package.
The publication of his manual on it in English language is
eagerly anticipated. In the mean time he published this manual
of LaTeX2e.
This is an interesting and enlightening publication. I have
been using LaTeX2e these thirteen years. There seems
nothing particularly new here for me. But the book is
well-written and well-organized. I imagine that it gives a good
working knowledge on LaTeX2e to the general readers.
But be warned; (1) the book's index is not so exhaustive as
Knuth's "TeX Book", and (2) the book is printed in
black-and-white format, whereas the author clearly has a more
varied colorful presentation in his mind.
