## Further information

For a general introduction to LATEX, including the new features of LATEX2e, you should read LaTeX: A Document Preparation System by Leslie Lamport [3].

A more detailed description of the new features of LATEX, and an overview of more than 150 packages, is to be found in The LaTeX Companion by Michel Goossens, Frank Mittelbach and Alexander Samarin [1].

The LATEX system is based on TEX, which is described in The TEXbook by Donald E. Knuth [2].

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 LaTeX2e for Authors describes the new LATEX document features; it is in `usrguide.tex`. The guide LaTeX2e Font Selection describes the LATEX font selection scheme for class- and package-writers; it is in `fntguide.tex`. Configuring LATEX is covered by the guide Configuration options for LaTeX2e in `cfgguide.tex` whilst the philosophy behind our policy on modifying LATEX is described in Modifying LaTeX in `modguide.tex`.

We are gradually turning the source code for LATEX into a LATEX document LaTeX: the program. This document includes an index of LATEX commands and can be typeset from `source2e.tex`.
