Impact factions: assessing the citation impact of different types of open access repositories

Abstract

Institutional repositories (IR) maintained by research libraries play a central role in providing open access to taxpayer-funded research products. It is difficult to measure the extent to which IR contribute to new scholarship because publisher self-archiving policies typically require researchers to cite the “version of record” of a manuscript even when an IR copy is accessed to conduct the research. While some studies report an open access (OA) citation advantage resulting from the availability of self-archived or “green” OA manuscripts, few have sought to measure an OA citation effect of IR separately from disciplinary repositories, including arXiv and PubMed Central. In this study, the authors present a bibliometric analysis examining correlations between search engine performance of items in IR, OA availability from different types of repositories, and citations. The analysis uses a novel, open dataset of IR access and usage derived from five months of Google search engine results pages (SERP) data, which were aggregated by the Repository Analytics and Metrics Portal (RAMP) web service. Findings indicate that making OA copies of manuscripts available in self-archiving or “green” repositories results in a positive citation effect, although the disciplinary repositories within the sample significantly outperform the other types of OA services analyzed. Also evident is an increase in citations when a single manuscript is available in multiple OA sources.

Citation Impact of Institutional Repositories in Selected Higher Learning Institutions in Tanzania

“…The advancement of Information Communication Technology (ICT) has changed how institutions collect, store, access, and disseminate scholarly outputs. ICTs have enabled the development, adoption, and use of Institutional Repositories (IRs) (Wheeler et al, 2022). An Institutional Repository is a database that collects, organises, manages, and disseminates electronic scholarly outputs of researchers, students, and staff of the relevant institution (Muneja & Ndenje-Sichalwe, 2017).…”

“…Europe and America were the first adopters of the IR initiatives, and then other continents adopted them later (Nunda & Elia, 2018;Wheeler et al, 2022). The IR initiative was pioneered by some countries, such as Germany, Netherlands, and Norway.…”

“…The increased number of IRs in Tanzania has led to the need to understand their impact, thus justifying their implementation, maintenance, and improvement. The IR impact refers to how the publications archived in the IRs are visible, used, accessed, and cited (Ndhlovu, 2021;Wheeler et al, 2022). The IR impact is measured through various metrics such as visibility, accessibility, downloads, usage, and citations.…”

“…This study has focused on measuring the impact of IRs through the citations of the IR content. Citation determines the quality of scholarly works and is the core aspect in which authors, institutions, and IRs can be evaluated (Caon et al, 2020;Liskiewicz et al, 2021;Wheeler et al, 2022).…”
