I took some time to explore these resources. What I found most interesting is that there are a number of affiliated courses in other countries--there isn't just the copyright course at Harvard, but other courses have taken the original content and modified it for their own contexts. This is really important because copyright differs so much from country to country. Many of the theoretical ideas are the same, but the particular cases and specific provisions in law clearly differ.
Some of the affiliated courses seem to be using a lot of the same material from the Harvard course, including the US court cases, and then adding in a few local cases and examples (see, e.g., this example from Italy). Some seem to just be using the Harvard materials exclusively without the local additions.
This could be a place to see some specific examples and court cases from various parts of the world, except that many of the content from the affiliated courses is hard to deal with (see below).
A number of the courses have their materials hosted on a Harvard Law platform called H2O, and it's very hard to navigate and read...each item seems to open in a different tab on my browser and then you can't get back to the higher level items you started with unless you go back to the earlier tabs. It's kind of frustrating to try to go through.
This resource is relevant to many aspects of unit 2 because it includes information on quite a few of the concepts discussed therein.
