A smaller update today (and one which will be more usual as the school year begins to start up again in the U.S.). This update has a wide variety of sites, including two blogs, an online course, journal, and a depository of digital texts. The Notre Dame Medieval Studies Research Blog appears particularly interesting as graduate students and faculty update the blog regularly with they research.
With this update, we not have a total of 145 links (and we still have roughly 200 more lined up!).
