Open Access and Citation Impact: Modality, Funding, Publisher, and Disciplinary Trends at the University of Kentucky

Abstract

As publishers and libraries attempt to align business models and collection strategies to an everincreasing open access (OA) publishing landscape, both have found that the message of open access citation advantage (OACA) resonates with current and prospective authors. Despite its widespread promotion and acceptance, however, OACA is not universal and is subject to ongoing debate. This quantitative study contributes to the OACA debate and research with a longitudinal focus on citation data from journal articles published 2018–2021 by University of Kentucky-affiliated authors.
The article and citation data for University of Kentucky-affiliated authors are supplemented with
University of Kentucky College and departmental data, providing valuable local context. In addition
to author-level departmental data, this study also considers traditional confounding variables often
investigated in OACA studies, such as OA modality, funding, and funding source, and introduces
journal publisher as a variable for OACA analysis.
