Non-accessible content

Despite our best efforts to ensure accessibility of the Minerva website, we are aware of some limitations, which we are working to fix. Below is a description of known limitations and potential solutions. Please contact us if you encounter an issue not listed below.

  1. Top navigation bar - keyboard accessibility: We are aware of some issues with the accessibility of certain links, particularly in the top navigation bar (the keyboard navigation through the tree menu does not function as expected and/or some links do not have alternate text). We plan to fix this issue by the end of 2023.
  2. Image links alternate text: We are aware that some of our image links do not provide alternate text for assistive technologies, such as text-to-speech. We plan to fix this issue by the end of 2023
  3. Content in PDF format: The content available in PDF format is not fully accessible to screen reader users. Due to resource constraints, only some documents in PDF have been duplicated in HTML format, compatible with assistive technologies. In general, those documents that are available only in PDF format cannot be converted easily to accessible versions due to copyright, technological, and/or resource complications.
