We support a huge range of data providers, from the smallest institutional repositories to the largest Open Access and preprint repositories such as PubMed Central and Arxiv. Each of these repositories have differing needs but one requirement for almost all of them is increasing the visibility and discoverability of their content. Being indexed by CORE is a key component in meeting these requirements. A recent study demonstrated that being indexed by CORE increases downloads from a repository by an average of 16%, and up to 32% in some cases.
