The ARVO journals have implemented the use of LaTeX for displaying mathematical equations in the XML versions of published articles. Previously, equations were often displayed as image files, so readers could copy the image as a whole, but could not manipulate any of the components individually. Now, because equations are coded, readers can copy select portions. The new process incorporates the features of MathJax
, including accessing the MathML code and TeX commands and resizing the math within the article.
