Is there any regulation governing the accessibility of research papers?
To the best of my knowledge, no such law has ever been passed (though I'm no legal expert).
Even if such a law was passed, however, enforcing it would likely be difficult or impossible:
- How could one assess the accessibility of a paper that can only even be understood by a tiny community of specialists?
- How could one ensure that an obscure or newly-invented notation can be translated to alternative formats?
- How could one effectively force scientists to invest time and energy in compliance, when funding agencies can barely even get them to do quick and easy things like pre-registering medical studies?
