accessible PDFs: best practice?

Hello everyone, this is Velix.

I am a geographer from Germany. I am a sighted person, but I create accessible documents (PDFs) at our research institute. An exchange with visually impaired people is therefore very important to me.

What I have noticed is that although there is a lot of specialist literature on the subject, there are only a few good example documents that do not contradict the current standards (e.g. PDF/UA-1).

For example, I currently have the problem of how footnotes should be correctly tagged in documents. I don’t want screenreader users to get into trouble with those notes.

Can someone link me to a few good documents that have footnotes and are easy to read with the screenreaders?

I’ll then borrow the implementation to make our scientific reports even more accessible.

Thanks in advance, Velix
