DAISY / printdisabled workflow is confusing. Is it current?

Problem

Currently only some records display the option to download a DAISY file in the left side bar.

I can see them in works or editions with archive.org identifiers and which have the status "Not in library" or "Read".

Relevant URL(s)

Not in library example: https://openlibrary.org/books/OL23174763M/Focus_and_background_in_Romance_languages

Read example: https://openlibrary.org/works/OL1796093W/Fair_Margaret

Evidence / Screenshot

Following through to the DAISY page e.g. https://openlibrary.org/books/OL24178528M/Fair_Margaret/daisy the links to the DAISY files 404s.

There's a lot of code, translatable strings, and FAQs relating to this feature,

• https://github.com/search?q=repo%3Ainternetarchive%2Fopenlibrary+daisy&type=code
• https://github.com/internetarchive/openlibrary/blob/8b0f5ecdd1cd7e7088c19ac8e3e1d60eca1a95eb/openlibrary/i18n/messages.pot#L2674
• https://openlibrary.org/help/faq/accessing

Reproducing the bug

• Expected behavior:

Following the instructions in the FAQ https://openlibrary.org/help/faq/accessing leads to two subject pages: https://openlibrary.org/subjects/accessible_book https://openlibrary.org/subjects/protected_daisy

Which lists books to Borrow and to Read.

I'd expect

• The accessibility FAQ to be up to date and describe the current offering for accessible material, whether its DAISY or something else.

• Borrowable books to have a DAISY / print disability option. Currently they don't. e.g. https://openlibrary.org/works/OL29983W/Little_Women

• Preview only books to have a print disabled option. https://openlibrary.org/works/OL554620W/The_Duke_and_I The above two examples are taken from the first six results on the 'protected_daisy' page.

• When I get to a /daisy page (by other means, because the FAQ and subject pages didn't help), the daisy.zip link should work: https://openlibrary.org/books/OL24178528M/Fair_Margaret/daisy It doesn't.

• Actual behavior: Stuff doesn't work as advertised. It's not clear if the instructions are out of date, or some things are not working as they should. It's not clear how a patron should access print-disabled material, or what one should expect.

As far as I know the links to https://www.loc.gov/nls/how-to-enroll/apply-for-nls-services/#eligibility-guidelines (which still resolve) all relate to current plans and these programs are still running.

Archive.org still offers protect DAISY files, for that item: https://archive.org/details/cu31924021992015

but there isn't a pre-generated one at the URL offered by the OL daisy page.

Also, I now notice the main search page has a print-disabled option. In the context of this issue I don't see what the filtering does, or how the results provide print-disabled access (any more or less than any other search result item) https://openlibrary.org/search?q=happiness&mode=printdisabled&subject_facet=Protected+DAISY
