Current membership criteria are as follows. The journal must:
- satisfy the 5 Fair Open Access Principles;
- allow the possibility for authors to publish their paper in English;
- clearly display its membership of the network on its homepage;
- be invited by the steering committee.
Membership is reviewed via an annual audit. We expect that the membership criteria will become more stringent over time – for example listing in DOAJ is very likely to be required for 2019. The steering committee reserves the right to make its own judgments on whether a journal is sufficiently international, large or sustainable.
