In recent years, large libraries have jumped on this trend, producing recorded author events, tutorials, and promotional videos; since the pandemic began, the popularity of online videos has exploded even further. Ubiquitous as it is, much video content remains inaccessible to viewers with disabilities, particularly those who have lost vision or hearing. Only a small fraction of online videos have basic accessibility features, such as captions, and even those are rarely fully accessible to all viewers.”
