“Subject indexing in humanities: a comparison between a local university repository and an international bibliographic service”, Journal of Documentation, May 2020.

… the use of subject index terms in humanities journal articles [is] not supported in either the world’s largest commercial abstract and citation database Scopus or the local repository of a public university in Sweden. The indexing policies in the two services do not seem to address the needs of humanities scholars for highly granular subject index terms with appropriate facets; no controlled vocabularies for any humanities discipline are used whatsoever.
