When I try to use a screen reader (Apple VoiceOver) on the exported PDFs of finding aids, it isn't able to read the document. The text appears to be locked, meaning also that a researcher cannot copy and paste from the text for other research purposes. The PDF export by default should be more accessible.
For future reference: https://www.w3.org/TR/WCAG-TECHS/pdf.html
Per Dev. Pri. - needs specification on whether it’s for both PUI and SUI PDFs. Will check later!
OK - I’m using the Apple VoiceOver software and both the PUI PDF and Staff PDF appears to be locked (like an image) and unreadable. However, the staff PDF appears to be more structured in the side menu, which is helpful for sighted people to jump to content (preferable), but still isn’t read by a screen reader.
