LaTeX

LaTeX is the high-quality document preparation system (based on TeX) for technical and scientific publishing.

LaTeX is your high-quality document preparation system, built on Donald Knuth's TeX typesetting engine. It operates on a descriptive markup language (not a WYSIWYG editor) to separate content from presentation: this is a key differentiator. This approach makes it the de facto standard for technical and scientific publishing, efficiently managing complex elements: think advanced mathematical equations, automated cross-references, and robust bibliography generation. The current stable version is LaTeX2e.
