The Links tool enables you to provide links to URLs, web sites, or Quicklink to areas in your course offering or files that are useful for your course.
You must organize links into categories; for example, a psychology course might provide the link categories General, Psychology, Reference Materials, Online Publications, etc. Categories enable better organization of links and enable users to quickly find the information that they need.
