Eric Priest has self-archived "Copyright and the Harvard Open Access Mandate" in SSRN.
Here's an excerpt:
This Article argues that permission mandates can create legally enforceable, durable nonexclusive licenses. First, it argues that although there are important justifications, including academic freedom concerns, for recognizing the controversial “teacher exception” to the work for hire rules for scholarly articles, such an exception may be unnecessary because a strong argument also exists that much scholarship is produced outside the scope of employment for work for hire purposes. Second, it argues that permission mandates provide sufficient evidence of the grantor's intent and the rights granted to create effective nonexclusive licenses. Third, permission mandates satisfy the requirements of § 205(e) and establish the license's priority over the subsequent transfer of copyright ownership largely because they fulfill the underlying purposes of § 205(e) by providing sufficient evidence and notice of the license to potential copyright transferees (typically academic publishers).
