AMS-TeX is a TeX macro package based on Plain TeX: it provides many features for producing more professional-looking maths formulas with less burden on authors.

This is the final archival distribution of AMS-TeX. AMS-TeX is no longer supported by the AMS, nor is it used by the AMS publishing program. The AMS does not recommend creating any new documents using AMS-TeX; this distribution will be left on CTAN to facilitate processing of legacy documents and as a historical record of a pioneering TeX macro collection that played a key role in popularizing TeX and revolutionizing mathematics publishing. AMS-TeX is the historical basis of amslatex, which should now be used to prepare submissions for the AMS.
