The mission of the Scientific and Technical Information Exchange (STIX) font creation project is the preparation of a comprehensive set of fonts that serve the scientific and engineering community in the process from manuscript creation through final publication, both in electronic and print formats. Toward this purpose, the STIX fonts will be made available, under royalty-free license, to anyone, including publishers, software developers, scientists, students, and the general public.

By making the fonts freely available, the STIX project hopes to encourage the development of applications that make use of these fonts.

The STIX Fonts project is an activity of the STI Pub companies.
