This morning, Deyan Ginev announced on the LaTeXML mailing list that the first alpha version of LaTeXML with LaTeX to EPUB support is now available. This is a very good news for people willing to encourage researchers to move from offline formats to more modern Web formats. Although, some people had already been successful to combine LaTeX-to-XHTML converters and XHTML-to-EPUB converters, this is the first tool that I'm aware of that can do the direct LaTeX to EPUB3 (XHTML+MathML) conversion. I already mentioned a couple of Gecko-based EPUB tools in my previous blog post, so let's have a look at three of them. Feel free to mention more Gecko-based EPUB tools in the comments, I'm particularly interested to hear about FirefoxOS applications that would be similar to Apple's iBooks.

I have updated the LaTeXML samples based on Boris Zbarsky's thesis that we demonstrated at the Innovation Fairs in Santa Clara & Brussels. This shows how to generate the traditional PDF version, the Web version, the Web version with MathJax fallback and now the EPUB version! Here are some screenshots using the Firefox extension Lucifox:

I have intentionally not shown the diagram that are incorrectly converted by LaTeXML due to missing Xy-pic support (this is still in development). However, Gecko supports mixing SVG and MathML via the foreignObject element so this would not be a problem for Gecko-based EPUB readers. Here are some screenshots of an ebook about regular polygon that can be constructed with compass and straightedge that I have created with the help of itex2MML. They are viewed in EPUBReader which is another Firefox extension:
