Here is a video showing the difference between how a screen reader reads aloud a web page which has inaccessible hyperlink text and one with accessible hyperlink text.
To add a link in Gutenberg:
To add a link with meaningful text in LibGuides:
Select "Link" from the drop-down menu
If you add a link in a Rich Text/HTML box
Make sure the emails you send are accessible. If you include a link in an email, these links also need to have meaningful text.
When creating citation lists which require urls to be spelled out or the use of DOIs, what you can do is make the titles of the citation items the clickable links, since the titles will be meaningful link text, and then still include the actual urls or DOIs but don't have them be active links. This way the urls or DOIs won't be read aloud by screen readers when users are calling up a list of links but will still be available to all users of the citation list.
