This document is an unofficial reference manual for LaTeX, a document preparation system, version as of September 2009. It is intended to cover LaTeX2e, which has been the standard version of LaTeX for many years.
LaTeX is implemented as a macro package for Donald E. Knuth's TeX typesetting program. LaTeX was originally created by Leslie Lamport; it is now maintained by a group of volunteers (http://latex-project.org). The official documentation written by the LaTeX project is available there. Again, the present document is unofficial and has not been reviewed by the LaTeX maintainers.
