I am a blind undergraduate student in math. I use screen reading software, which uses synthesized voice to read the screen content aloud, read and write math.
Due to limitations in presentation-centric formats such as PDF and MathJax, screen readers cannot properly handle most of the mathematical content contained in them.
This means that, for the most part, I can only correctly access mathematical documents in their source format, such as LaTeX; This severely limits the resources they have access to study.
Fortunately, there are some excellent online mathematical resources that include content sources, such as Wikipedia and NLab, but sometimes they are not enough by themselves to learn a topic well.
Sometimes I have been fortunate to communicate with kind professors and editors about private textbooks, which they were able to provide in source format;
but in general it is very difficult to find other good learning resources available as a source.
Another good resource is Arxiv, which often allows you to download the source of an article, but it is very difficult to search between specific educational resources through the mountain of articles.
What would be really good is a complete list by topic of mathematical educational resources that people have made available online as a source;
and this is what I would like this question to become.
So: if you have (or know) class notes, textbooks or the like, which are available online as a source, through Arxiv or elsewhere, post it as an answer, and I will keep the question updated with a categorized list
(Note: no special processing is necessary for the LaTeX screen reader to be friendly).
Thanks in advance for making life easier for blind math students.
PS I hope this is an appropriate place to make this post; I'm sorry in advance if it isn't.
