[1/2] Ulrike Fischer showed a summary of the #TeXLaTeX News including a preview for the next release in June.

Of course she included achievements of the tagging project which included the new template based implementation of sectioning commands.

And the status of accessible math typesetting using #MathML https://www.latex-project.org/news/2026/03/05/PDFA-press/ which is a huge step towards completely accessible documents.

PDF Association’s press release: Accessible math in PDF – finally!

Press release by the PDF Association (PDFA) on: Accessible math in PDF – finally!

The PDF Association @PDFassociation announced their "all-new" Product Showcase in January. The new interface provides an improved search, and the ability to search by product types, standards, and features.

For example, you can search for only open source or no-cost solutions. Or ones that offer Tagged PDF or PDF/UA-1 or 2. Or filter the results to only list those who offer "Remediate Tagged PDF" service.

If you are confused about your schedule, here's a summary. The PDF schedules provided by the City of Toronto and Circular Materials are both correct. Some map areas have changed their pickup schedules: for example, Parkdale used to be Wed Day 2 and they have now switched to Wed Day 1. The PDF versions of the maps show these changes correctly. But the mobile app and website lookup function don't.

Folks affected by Day switches should have received special printed mail notices about these changes, but some didn't.

One disappointing note about the PDF calendars: while those on the city's site are visually identical to those on Circular Materials site, the ones used by Circular Materials are inaccessible and untagged. Why don't they use the same tagged versions that are on the city site? Who knows! Does Circular Materials even know about the AODA (Accessibility for Ontarians with Disabilities Act)? No they don't.

@ctietze I need to be able to make slides from #OrgMode files. But #Beamer cannot (and will not) be made to produce #taggedPDF output (thanks, @mxp). So rather than bang my head against #TeXLaTeX, I took a step back.

Org mode, LaTeX, and tagged PDFs: producing accessible documents

[Howell breathes a long relieved sigh]

Before and after.

Canvas' infamous automatic ratings of #accessibility. In the proud bean-counting brain-dead tradition of provosts and deans, the thing they can measure is the thing we must make number-go-up.

Lots of steps to get Debian to run #texlive2025. Then a few steps to configure Org properly to export #TeXLaTeX that produces #taggedPDF output.

I promise the Fediverse I will write up all the steps and make a blog post.

tl;dr thanks to Dr. Kenny Ballou at Cal State San Marcos https://kennyballou.com/blog/2025/08/tagged-pdfs-org-export/index.html

Okay, gang, more vacation-work. Going all-in on #accessibility, and it appears I need #texlive2025 to produce semantically #taggedPDF output from #TeXLaTeΧ. I'm still on #Debian12 so here goes.

# may take several hours to run

LOL

Advice or pointers to resources welcome. Obviously the final goal is #OrgMode export in #Emacs.

A couple recent PDF software releases you might have missed:

1. PAC 2026:
A new version of the free PAC (PDF Accessibility Checker) includes AI-assisted checks. [1]

2. Stirling PDF v2:
This open source set of PDF manipulation tools is now available as a desktop app [2]. Download available for Windows/Mac/Linux. [3]

Big update to the annotated edition of G.H. Hardy's ‘A Mathematician's Apology’: the PDF is now *tagged* (plus various minor improvements).

(A #TaggedPDF contains extra semantic information to assist screen-reading software etc.)

The new version is available (#OpenAccess as always) at https://archive.org/details/hardy_annotated

The LaTeX tagging system is still under development [https://latex3.github.io/tagging-project/], but I have been making progress in adapting my LaTeX styles to be tagging-compatible.

For the annotated ‘Apology’, I also had to re-implement a subset of the functionality of the "manyfoot" package (which is currently not tagging-compatible), because there are two different kinds of footnotes in the annotated ‘Apology’. (Hardy's original footnotes and the annotations.)

Although the PDF passes VeraPDF validation, there may of course be mistakes in the tagging. Feedback, especially from users of screen readers, would be much appreciated, especially because I now hope to add tags to ‘Form & Number: A History of Mathematical Beauty’ [https://archive.org/details/cain_formandnumber_ebook_large].

‘Bertrand Russell & Trinity: A college controversy of the last war’ is a pamphlet written by G.H. Hardy in 1942, giving an account of the dismissal of Russell from his Trinity College lectureship in 1916 following his criminal conviction for anti-war political activity. (Hardy was at the time a fellow of Trinity and opposed Russell's ouster.)

I have uploaded a re-typeset version of Hardy's pamphlet to the Internet Archive [https://archive.org/details/hardy_russellandtrinity].

Creating this version was an exercise for me to learn how to (start to) adapt my LaTeX styles to the new interfaces created by the ongoing LaTeX tagging project [https://latex3.github.io/tagging-project/]. (A #TaggedPDF contains supplementary information to assist screen reading software, data extraction, etc.)

Also, Hardy's work is in the public domain; there seemed to be no downloadable ebook version of this pamphlet; and I thought that it would be a useful companion to the ‘Annotated Mathematician's Apology’ [https://archive.org/details/hardy_annotated].

I have made available the #LuaLaTeX source code on #Codeberg, in case anyone is interested in how the style was created: https://codeberg.org/ajcain/hardy_russellandtrinity
