By now you will have acquired the course pack, and hopefully studied the downloadable syllabus (pdf) (doc) very closely, especially as it contains sections that are not to be found on this site. In addition, please check the site regularly, for new resources added to the sessions page, and check this blog as well.
Any new resources are supplemental, not required, and may in some cases be used by the course coordinator in presentations for seminar purposes. Those undertaking research in a given topic area should find the additional resources to be useful.
Finally, seminar participants should glance at the RSS feeds, documents, and videos in the sidebars, to follow news or gather materials for their own research.
This will be an exciting and challenging course, I am glad you joined!
