TeX Resources

Warning: U.S. Government requirements concerning certificates for web servers have become more restrictive, and many sites are scrambling to catch up. Some URLs on this and related pages may be temporarily blocked until the proper certificates can be installed. Please be patient.

The TeX program

TeX software is available from a number of sources:

• freeware or shareware
• commercial TeX vendors

LaTeX is an integral part of all "standard" TeX distributions.
The AMS document classes and the amsmath package are included among the "required" LaTeX packages.

Extended TeX engines

• pdfTeX generates pdf output instead of dvi.
• XeTeX supports the direct use of system fonts.
• LuaTeX is based on Unicode and embeds Lua (a scripting language) and MetaPost to permit operations not easily accomplished with the basic TeX engine; v1.0 was released in late 2016 and included in TeX Live 2017.
