Harvard Law School is preparing to offer a free course through edX -- the platform Harvard University uses for MOOCs (massive open online courses). But as The National Law Journal  reported, the law course (on copyright) won't be totally open or massive. Enrollment will be limited to 500. The course description  explains the rationale behind the limit: "Enrollment for the course is limited, in keeping with the belief that high-quality legal education depends, at least in part, upon supervised small-group discussions of difficult issues. Fidelity to that principle requires confining the course to the number of participants that can be supervised effectively by the 21 teaching fellows. The limit on the enrollment does not mean, however, that there will not be access to the course materials. On the contrary, all of the readings and recorded lectures used in the course will be made available to the public."
