In private negotiations with institutions, some journal publishers are trying to increase embargo periods on author manuscript deposits into repositories beyond what is publicly stated in their open access policies.
SPARC, SPARC Europe, JISC, OAIG, and COAR have issued statements strongly urging institutions not to enter into private agreements with publishers that override existing publisher policies or previous licensing agreements.
The statements also urge publishers to dispense with additional restrictions and regulations that hinder deposit and accessibility of scholarly work by confusing users and complicating repository maintenance. See:
