Ask yourself these questions when writing descriptions:
This NYU LibGuide Accessibility Remediation Summer, 2020 Guide description is:
"Internal Division of Libraries resource guide to support Summer, 2020 accessibility (a11y) remediation."
The "Describe Your Guide" page description is:
"How to include a Guide description for access and discoverability."
Include guide and title descriptions as a checklist item in training for new LibGuides users.
The page description feature is pretty buried in the system so authors may not know about it unless prompted or included in your organizations style guide.
