Small, emerging and applied research fields (e.g., internet regulation, media informatics) particularly strive for a dynamic and diverse publishing ecosystem, without (high) article processing charges and opaque publication processes. Thus, the 18 months “InnOAccess” project (Humboldt Institute for Internet and Society, together with ZBW – Leibniz Information Centre for Economics) seeks to 1) improve the publication infrastructure of the open access and peer-reviewed journal “Internet Policy Review,” 2) articulate sustainable OA business models in the small sciences context, while 3) providing transferable solutions. First research results, including a statement on suitable OA business models for small science journals will be presented.
