What's inaccessible about LaTeX-generated PDF?

It used to be a problem that you couldn't cut and paste text from TeX-generated PDFs, and I assume this would be a problem for screen readers. I think the dvi->pdf conversion produced a PDF consisting mostly of coordinates and characters (in a non-standard encoding), which PDF readers couldn't put back together into words. This seems mostly fixed on recent pdfs, but I don't know if it's TeX (pdflatex?) or the readers that have gotten smarter.

Funnily, Donald Knuth's AoCP fascicles ship as postscript files, which Preview.app converts to PDFs that can't be copied from.

It's not at all fixed. It's slightly better than it was, but anything non-trivial (tables, columns) is often still unreadable.

If you're using a screen reader anyway, why not export to text instead of pdf? You're just wasting more storage for no benefit you can perceive.

This relies on what should be a reasonable assumption that the latex source is provided.

It's.. inaccessible. Try any screen reader you like. If you are lucky you will get most of the text out with some characters randomly broken. Columns often don't read in the right order, tables and maths are both unreadable.

Good luck reading a scientific paper on your phone without lots of zooming and scrolling around.

And that's somehow better in Word-generated scientific papers?

Actually, word produces PDFs which contain markup for screen readers, which make them much more accessible to blind people.

Good luck reading a scientific paper on your phone period. Many journals are now making available the full text of papers in straight HTML (possibly only for users of participant libraries, I don't know) but that still sucks.

I mean, it's a small screen.
