New Textbook and Video Content in Pre-A&P Outlines

Today I added some additional mini-icons to the Review Outlines for my Pre-A&P-Foundations in Science course.

The textbook references link to "open" textbooks from OpenStax and textbook content from Kahn Academy.  There is a new "book" icon that identifies these links.

There are also several new links pointing to videos from Kahn Academy, identified by the "video icon."
