For a general introduction to LATEX, including the new features of LATEX2e, you should read by Leslie Lamport [#!A-W:LLa94!#].
A more detailed description of the new features of LATEX, and an overview of more than 150 packages, is to be found in by Michel Goossens, Frank Mittelbach and Alexander Samarin [#!A-W:GMS94!#].
The LATEX system is based on TEX, which is described in The TEXbook by Donald E. Knuth [#!A-W:DEK91!#].
There are a number of documentation files which accompany every copy of LATEX. A copy of LATEX News will come out with each six-monthly release of LATEX, and is found in the files |ltnews*.tex|. The author's guide describes the new LATEX document features; it is in |usrguide.tex|. The guide describes the LATEX font selection scheme for class- and package-writers; it is in |fntguide.tex|. Configuring LATEX is covered by the guide in cfgguide.tex whilst the philosophy behind our policy on modifying LATEX is described in in modguide.tex.
We are gradually turning the source code for LATEX into a LATEX document . This document includes an index of LATEX commands and can be typeset from |source2e.tex|.
