TL;DR
This study compares the geographical and disciplinary coverage of open access journals across OpenAlex, Scopus, and WoS, revealing differences in inclusivity, regional biases, and alignment with the ROAD database.
Contribution
It provides a comprehensive comparison of OA journal coverage across three major databases, highlighting biases and the extent of inclusivity in each.
Findings
OpenAlex indexes significantly more OA journals than WoS and Scopus.
WoS and Scopus show similar coverage patterns, favoring Europe, North America, and Oceania.
OpenAlex offers broader coverage but still exhibits regional biases.
Abstract
This study aims to compare the geographical and disciplinary coverage of OA journals in three databases: OpenAlex, Scopus and the WoS. We used the ROAD database, managed by the ISSN International Centre, as a reference database which indexes 62,701 OA active resources (as of May 2024). Among the 62,701 active resources indexed in the ROAD database, the Web of Science indexes 6,157 journals, while Scopus indexes 7,351, and OpenAlex indexes 34,217. A striking observation is the presence of 25,658 OA journals exclusively in OpenAlex, whereas only 182 journals are exclusively present in WoS and 373 in Scopus. The geographical analysis focusses on two levels: continents and countries. As for disciplinary comparison, we use the ten disciplinary levels of the ROAD database. Moreover, our findings reveal a striking similarity in OA journal coverage between WoS and Scopus. However, while…
