Greetings. I think "Course" or "Class" should be de rigueur for item types. Nothing else quite fits, and it's troublesome to fiddle with "Presentation" or "Web Site" for such things. If I'm citing a single lecture from a course, "Presentation" is sort of okay; if I'm citing something posted to an online course, "Web Site" can be okay. But if I want to cite a whole course, nothing quite fits. And even "Presentation" is not ideal for a single lecture, as it doesn't include "Course title," "Course ID," or "College/University/Institution." I think this option should be added ASAP. Thanks!
