Requests to publishers
Where explicit permission to mount a full-text version in a repository is not given, or even denied, the EC and ERC Open Access mandates require the author to contact the publisher. The author should inform the publisher of the EC or ERC Open Access requirements for his/her article, and ask for an exception to the publisher’s normal policy to enable compliance with the mandate. It is important to obtain this permission in writing.
When writing to publishers, it is better to write to the editor or officer in charge of authors' rights if possible, rather than to a general publisher's email for permissions for re-use of published material. It is important that the request be seen as coming from the author and is part of the publisher/author relationship.
The EC provides a set of resources, among which a model for a publishing agreement addendum and covering letter to the publisher; these can be found here.
