The OpenAlex database in review: Evaluating its applications, capabilities, and limitations

Abstract: This systematic review examines OpenAlex, focusing on its technical features and its applications within science studies and scientific information sources. The paper offers a critical perspective on OpenAlex’s role in democratizing and promoting equity in access to scientific information. A total of 146 articles published between 2022 and 2025 are analyzed and classified by functionality and application, including AI-based validation processes. Findings reveal the rapid adoption of OpenAlex as an open alternative to commercial databases, particularly across the Global South. However, notable metadata limitations—especially regarding affiliations, languages, and document types—still affect analytical reliability. The study highlights key opportunities and challenges for researchers, libraries, institutions, and the technical community, emphasizing the need for complementary validation and responsible assessment strategies.
