Presenting mathematical formulae correctly has always been tricky for publishers, whatever the medium. It's especially difficult when you are delivering a range of mathematical content via multiple online platforms. An article in the October/November issue of Research Information reports on the development and progress of MathJax, a universal standard for online display of mathematical formulae. It enables all web browsers to display Mathematical Markup Language (MathML) more easily. Future plans include and enhanced interface and linewrapping of equations, as well as third-party contributions and integration with other software.
