The collection gathers resources dedicated to people with disabilities, particularly visual and hearing impairments. The resources were adapted by a team of accessibility specialists so that the text of publications, information conveyed graphically (e.g. through photos), mathematical formulas, diagrams and charts are accessible to a person using a screen reader and a braille display. Video resources, in turn, were enhanced with extended captions, enriched with additional audio tracks describing the image, and processed to allow better perception of key visual details.
