I think we were discussing "libraries" in this forum a while ago. That idea had to do with creating a course and placing a library of lessons on specific topics.
Can't you put a Google search that will point to everything in your domain? Then in Moodle put it in a sticky block, or some sort of HTML block in a course, or as a link to a resource that will open it's own window?
Your post probably should be in General problems. Some hot shot techie should be able to help you there
