The current issue of TUGboat (32.2, 2011), the Communications of the TeX Users Group, has eight papers in a section called "Electronic Documents," dealing with various issues affecting the relationship between LaTeX and the latest fashions in on-line publishing and mobile devices. The ePub format, standard on most e-readers, remains a significant rival to the dominance of PDF, widely used for long-term document storage, and several of the articles address the challenges ePub presents.
All are worth reading; I single out these two as especially useful:
- Alan Wetmore, "e-Readers and LaTeX," reviews current e-readers and the problems they have displaying PDFs.
- S. K. Venkatesan, "On the use of TeX as an authoring language for HTML5," proposes a TeX syntax for generating HTML5.
A third noteworthy paper is Axel Kielhorn's "Multi-target publishing" (based on a German original, also 2011), which describes pathways from LaTeX to PDF or ePub output by way of John Gruber's Markdown language (currently at http://daringfireball.net/projects/markdown/). The chief element of these pathways is Pandoc, on which see http://johnmacfarlane.net/pandoc (accessed 20120107); the main Github repository is currently at https://github.com/jgm/pandoc (accessed 20120107).
