A contemporary author writing an article for “dual presentation” has in mind both the classical printed presentation of an article and the modern web form of an article based on HTML.

There are two main approaches for achieving dual presentation that are relevant to the TeX community.1

Both methods present challenges to authors who have been accustomed to using LaTeX.

Since mid-2002 the second-generation form of HTML that supports mathematical content has been supported by the two most widely deployed web browsers, but not many articles seem to have appeared on the web in this form so far. The most likely reason is difficulty of production.

This talk will address the use of “generalized LaTeX” to produce dual content from a single LaTeX-like source. This method combines the reliability of XML document transformation with many of the conveniences available when writing LaTeX markup.
