CWI intends to make its scientific output available through Open Access. Specifically this means that all output should be present in our SOS.
In the life cycle of a scientific publication the following three stages can be distinguished: preprint, post-refereeing author version and publisher’s version.
We would like to have all preprint in the CWI-repository. Not mandatory, but when an author uses a preprint server like ArXiv then also use the repository. Preprints get a technical report and version number. A possible embargo period can be taken into account. Later versions can be uploaded. Preprints from the CWI repository are harvested by NARCIS and can be forwarded to other repositories like ArXiv.
Post refereeing author version.
CWI authors are obliged to make a full text available in the CWI repository. Only publications complying with these demands are counted as CWI output. This is the immediate green NWO enforced as of 1 January 2015.
Publisher’s version, certified by a publisher.
When using a so-called overlay publisher this version remains in the repository. In case of an open access publication the work is freely available (golden road). Traditional (closed access) publications are not encouraged but are allowed.
An open access publication often requires publication fees, the Author Processing Charges (APCs). For NWO projects and some EU projects these fees are part of the project funding. Other APCs can be funded through a central budget managed by ID. Excluded from this funding are rogue journals and hybrid journals.
