.Open Mathematical Typesetting: AMS-TeX Symbols
. Introduction
The following is an attempt to classify and clarify some of the symbols promoted by the American Mathematics Society for use with Donald Knuth's TeX mark up system.  This classification has no claims to completenes or correctness.  Its just my attempt to order the chaos of an alphabetic listing of symbols.
