Assessing Third Party Vendors for Accessibility
Before purchasing electronic resources, you should verify if they are accessible and not take the vendor's word (or VPAT).
What questions should you ask to assess the accessibility of a vendor's product?
You'll also want to conduct manual testing based on those responses.
Web Accessibility Policies
Some public libraries (Sacramento, Chicago) are officially organized and structured as a government entity underneath and adopt policies of their general city.
Others (NYPL) that are self managed and adopt their own web accessibility policies.
