Earlier this year there was news that the Wellcome Trust would be introducing a tougher stance on compliance with their open access policy, and they have now outlined the steps they will take:
The Wellcome Trust today announces that it will be strengthening the manner in which it enforces its open access policy with immediate effect. Failure to comply with the policy could result in final grant payments being withheld and non-compliant publications being discounted when applying for further funding.
The Guardian also reports on this new policy: Wellcome Trust to penalise scientists who don't embrace open access.
Support is available for St Andrews researchers who are in receipt of a Wellcome Trust grant. The Wellcome Trust has provided money to the University specifically to cover article fees for publishing in open access journals. The Trust also provides a list of frequently used journals with specific advice on how best to comply.
