The PDF Association has released the first edition of the Best Practice Guide: Math in PDF.

This guide, developed by the LaTeX Project Liaison Working Group (A collaboration between the LaTeX Project and the PDF Association) provides critical recommendations for authors and publishers to ensure complex mathematical and STEM content meets accessibility requirements and assistive technology users’ needs.

Comments and more general discussion of Tagging of STEM documents may be sent to the PDF Association at info@pdfa.org or as discussions at the LaTeX project tagging site.

Enjoy — Frank
