The Great Courses Plus is a streaming version of the Great Courses, both of which are offered by The Teaching Company. It is intended for people who want to learn about a subject they have an interest in but cannot find a full version of the course they want to learn about, or who simply want to make sure they have all of the information from a particular course available to them.

The extension can be used by anyone who has access to The Great Courses Plus. It is intended for use by Great Courses Plus users who can view the course pages on the website and want to create a link on the Great Courses Plus pages to the corresponding page on The Great Courses.
