Get Started with Annotations & Overlays

TextBookHub allows you to enrich your textbooks with commentary and other annotations via four features: highlighting, bookmarking, adding comments, and adding scribbles (pdf books only).

Instructors can further enrich textbooks through the use of overlays. Overlays are links to extra learning content. They are visible on the page via an icon and can be clicked to display their content.
