My screen reader has a hard time with PDF documents. As I delve into more niche textbooks, I increasingly find them only in print/PDF rather than EPUB.
This makes it difficult to learn when the screen reader's OCR is not good. Would it be fruitful to ask people for LaTeX versions of their textbooks or would this be poorly received? I write LaTeX content fairly often, so I think this should be easily comprehensible if I listen to it in bulk.
The issue may also be related to using scihub/libgen, which may have worse prints of the books/papers (although I've seen this in my purchased PDFs as well).
