The Association of Learned and Professional Society Publishers (ALPSP) together with the Professional and Scholarly Publishing Division of the Association of American Publishers (AAP/PSP) and the International Association of Scientific, Technical and Medical Publishers (STM) have issued a White Paper laying out general terms for the appropriate balancing of rights for academic journal publishing.  In particular, the White Paper notes that:

Academic research authors and their institutions should be able to use and post the content that such authors and institutions themselves provide for internal institutional, non-commercial research and education purposes; 

Publishers should be able to determine when and how the official publication record occurs, and to derive the revenue benefit from the publication and open posting of the official record (the final published article), and its further distribution and access in recognition of the value of the services they provide.
