Oxford wants disclosure from Oxford Open authors

Oxford University Press has tweaked the policy for its Oxford Open hybrid program.  The following is new as of yesterday or today:

Oxford Journals asks authors to state the source of funding used to pay the Open Access publication charge, after having a manuscript accepted. This provides transparency for readers, funding bodies, and the publisher. If appropriate the information will be added to the Acknowledgement section of the article. It is not compulsory to provide this information, but we encourage all authors to do so.

PS:  Oxford Open is the first hybrid program to adopt such a policy.
