Where can I find the symbol for ...
There is a wide range of symbols available for use with TeX, most
of which are not shown (or even mentioned) in (La)TeX books.
The Comprehensive LaTeX Symbol List (by Scott Pakin
et al.) illustrates over 2000 symbols, and details the
commands and packages needed to produce them.
Other questions in this FAQ offer specific help on kinds of
symbols:

- Browse info/symbols/comprehensive/; there are processed
versions in both PostScript and PDF forms for both A4 and
letter paper.
