STM has released the "STM Statement on Negotiating Rights for Institutional Repository Postings and Author Rights."
Here's an excerpt:
Recently some advocates for institutional repositories have noted that, in connection with the responsibilities that academic and research libraries may have for coordinating the scholarly output of author-researchers at their institutions, there are efficiencies to be gained in negotiating at an institutional level with journal publishers. . . .
STM publishers are of the view that content license negotiations deal appropriately with questions about the scope of content that will be accessible for each institutional subscriber as well as the scope of usage rights and relative costs for such accessibility and rights. These negotiations are often complex, especially given that in recent years efforts have been made to manage negotiations through procurement processes of different kinds. We hold the view that conflating author rights issues and institutional content licenses serves only to add greater complexity and possible legal uncertainty to such licenses without adding meaningful benefits for authors.
SPARC, SPARC Europe and COAR have issued a "Public Response on Behalf of SPARC, SPARC Europe and COAR Regarding Publishers Self-Deposit Policies."
Here's an excerpt:
We have recently noted that some journal publishers have sought to negotiate individually with universities and research institutes, seeking to increase embargo periods for authors depositing pre-prints of their articles into repositories, and requesting embargo periods that go beyond what is already stated in the publishers' own policies.
We strongly urge institutions not to enter into individual agreements with publishers that supersede the existing policies of the publisher or any previous licensing agreements.
We also call on the publishers not to further hinder the deposit—and accessibility—of pre-prints with additional restrictions, regulations and policies. Proliferation of this practice will result in an environment that is confusing to navigate for end users, and increasingly difficult for individual institutions to effectively maintain.
