STIX Fonts project
The STIX Fonts project is a project sponsored by several leading organizations to provide, under royalty-free license, a comprehensive font set of mathematical symbols and alphabets, intended to serve the scientific and engineering community for electronic and print publication. The STIX fonts will be available as fully hinted Type 1 and True Type fonts. 32.9% of the glyphs have been contributed by the project members. The commercial TeX vendor and TeX font foundry MicroPress has been contracted to create the additional glyphs. The STIX project will also create a TeX implementation. Goals also include incorporating the characters into Unicode, and ensuring that browsers can use them.
Members of the STIX (Scientific and Technical Information Exchange) Fonts project, known collectively as the STI Pub consortium, include the American Institute of Physics, the American Chemical Society, the American Mathematical Society, the Institute of Electrical and Electronics Engineers, the American Physical Society, and Elsevier.
According to the web site
The Font contents were assembled from a list of every character/glyph required for publication in the journals of the participating STI Pub companies. Every scientific discipline is represented in this list, as well as many other fields from the arts and humanities.
Most of the glyphs in the STIX Fonts have been designed in Times-compatible style. In addition to Times-compatible glyphs, some portions of the STIX Fonts include other design styles such as sans serif, monospace, Fraktur, Script, and calligraphic.
On July 10, 2006 the final set of glyphs were received from MicroPress. As of July 24, 2007 the official website announced "Final packaging in progress; font set beta release delayed until about 15 August".
ESSTIX
A precursor to the STIX project is the ESSTIX (Elsevier Science STIX) font, developed and later donated by Elsevier. It is currently available from the World Wide Web Consortium as part of the Amaya web browser ([1]).
