Thanks very much for all of these comments, which I’ve duly noted for Version 5.0 (to come out in June/July).
As for the history section more generally, I will very likely drop out the excerpt from Mark’s article and replace it with an excerpt from the Restatement (Third), Section 9, which sets out the basic history in much less detail (and regrettably with much less color) and does not explicitly refer to the early English or American case law. I liked a lot the discussion in Mark’s article of the cases because it brought out so many themes that would appear later in the course. But as first day introductory reading, I’ll admit that it is too detailed a history. (We do read the article in our advanced trademark seminar, however).
