{Access and accessibility}
{Jonathan Fine}
{The Chafee Amendment
\url{https://www.loc.gov/nls/about/organization/laws-regulations/copyright-law-amendment-1996-pl-104-197/}
to \acro{US} copyright law ``allows authorized entities to reproduce or
distribute copies or phonorecords of previously published literary or
musical works in accessible formats exclusively for use by
print-disabled persons.''

This wonderful legal exemption to copyright nicely illustrates the
relation between access (here to print works) and accessibility (here
production of phonorecords, i.e., audiobooks). Here's another
illustration.

Jonathan Godfrey, a blind Senior Lecturer in Statistics in New Zealand
wrote to the Blind Math list ``I used to use \TeX4ht as my main tool
for getting \HTML\ from \LaTeX\ source. This was and probably still is,
an excellent tool. How much traction does it get though? Not much. Why?
I don't know, but my current theory is that tools that aren't right
under people's noses or automatically applied in the background just
don't get as much traction.'' (\url{https://nfbnet.org/pipermail/blindmath_nfbnet.org/2021-January/009641.html})

Jonathan Godfrey also wrote to the BlindMath list ``Something has to
change in the very way people use \LaTeX\ if we are ever to get truly
accessible pdf documents. I've laboured the point that we need access to
information much more than we need access to a specific file format, and
I'll keep doing so. [\ldots] I do think a fundamental shift in thinking
about how we get access to information is required across most
\acro{STEM} disciplines.

This talk looks at the experience of visually impaired \acro{STEM}
students and professionals, from both the point of view of easy access
to suitable inputs and tools and also the generation of accessible
outputs, as pioneered and enabled by the Chafee Amendment.}
