This is nice, and good for HLS faculty, but a small clarification: HLS faculty publications (now to be open) are not the same as the student-published journals like "Harvard Law Review."

HLS faculty publish in many journals, some published by Harvard students, some not. Conversely, because of heavy subsidies from law schools, the student-published journals that make up the bulk of academic legal literature have historically been among the cheapest and the most open to free access.

The rest of the legal literature - primary sources like caselaw and (as reported here) statutes are not so inexpensive. But see Legal Information Institute, http://www.law.cornell.edu.
