The IISL has become a Trusted Source of the Diamond Discovery Hub. The DDH is a service of the European Diamond Capacity Hub (EDCH) that improves the visibility and discoverability of Diamond OA Journals.
As a prerequisite to get listed in the DDH, a journal must fulfil the six Diamond Criteria.
- Persistent identification
- Scholarly journal
- Open Access with open licenses
- No fees
- Open to all authors
- Community-owned
The IISL's two journals (Oñati Socio-legal Series and Sortuz) meet these criteria, and they are both indexed in the DDH.
