I recently reworked my LaTeX template underlying my CV to be compliant with PDF/A-3U, and now I keep noticing chatter about PDF/A compliance or PDF accessibility in my feeds.

Let's collect notes here.

Accessibility of STEM documents

• https://tex.social/accessibility-of-stem-documents-talk-at-pdf-days-2025-in-berlin - blog post
• https://pdfa.org/the-winning-technical-poster-at-pdf-days-europe-2025 - all posters from the PDF Days Europe 2025 conference (many of them are about accessibility), very interesting!
• https://pdfa.org/presentation/tagged-and-accessible-pdf-with-latex-revisited - session at the same conference on "tagged and accessible PDF with LaTeX" with references to several works by the core LaTeX developers.
