-HTML-based textbooks are configured at the course level in the policy file.  The JSON markup consists of an array of maps, with each map corresponding to a separate textbook.  There are two styles to presenting HTML-based material.  The first way is as a single HTML on a tab, which requires only a tab title and a URL for configuration.
