The presence or absence of publishers in large bibliographic databases highlights tangible and symbolic differences between small and large publishers, underlining their diverging incentive structures. To assess these differences, this contribution explores reference data from small (open access) publishers and their journals in the Web of Science and Scopus. The analysis focuses on references that are not indexed in these databases and examines them from a text-as-data approach. The study frames two dimensions of relevance - visibility and impact - as proxies for assessing the scholarly bibliodiversity represented by small (open access) publishers. |
