NICE Technologies also has an online database of SGML vendors and products ( local archive copy). See also the detailed software summary for 207 products extracted from the technical report of Eila Kuikka and Erja Nikunen : (a) the full bibliographic entry, or (b) the overview in the 'Commercial SGML Software' page.
As a supplement to the links and information provided on public SGML software below, readers should consult Steve Pepper's 'Whirlwind Guide to SGML Tools and Vendors.' See the main bibliographic entry for the Whirlwind Guide for a document abstract and detailed information about its contents. The wealth of SGML software made freely available for public use is evidence of that ethos.
Priority is given to 'public' SGML/XML software in this document database since the scope of interest is mainly the Internet, where the ethic of public gift is highly esteemed.
