Green and gold open access citation and interdisciplinary advantage: A bibliometric study of two science journals - ScienceDirect

This bibliometric study quantified the impact of different open access (OA) implementations on the number and subject diversity of citations to articles. The study compared two partial OA journals and found that green (institutional repository) OA articles received up to 106% more citations on average than gold (publisher provided) OA or non-OA articles. OA articles received up to 36% more diverse (interdisciplinary) citations than non-OA articles. This result could inform libraries in their decisions regarding OA, specifically the continued importance of institutional repositories. The results will also assist librarians in educating faculty on the benefits of OA.
