The TeX Users Group (TUG) was founded in 1980 to provide an organization for people who are interested in typography and font design, and/or are users of the TeX typesetting system invented by Donald Knuth.
TUG is a not-for-profit organization by, for, and of its members, also representing the interests of TeX users worldwide. It is almost entirely member-supported, so if you use any TeX-related programs (TeX, LaTeX, ConTeXt, Metafont, MetaPost, Texinfo, et al.), please consider joining TUG (or any other TeX user group). The membership benefits include our journal TUGboat (available both in print and online), as well as the TeX software collection TeX Live, proTeXt, MacTeX, and more.
The Comprehensive TeX Archive Network (CTAN) is the primary repository for TeX-related software on the Internet. CTAN has many thousands of items; the TeX Catalogue and CTAN search page can help you find what you need.
