Abstract
Radical changes are taking place in scientific publishing, driven by mandates from major research funders both in the UK and elsewhere. The publishing landscape is changing, and open access is increasingly being seen as a viable alternative to subscription-based business models. Although many issues are yet unresolved, even the large commercial publishers are developing stables of open access journals. To reach a wider audience, and to increase appeal to potential contributors deciding where to publish, the Bulletin has now become an open access journal with effect from this issue.
