Literature reviews provide comprehensive overviews of research on a given topic, serving as a foundation for future studies and uncovering new insights by situating findings within a broader context. However, little research has examined these reviews as a collective body. The landscape of review studies on health information behavior and how they have evolved over time was explored. To achieve this, a review of reviews was conducted using a sample of 91 review studies identified through the Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagram. The findings reveal that while some researchers are well-integrated into co-authorship networks, most authors tend to work independently when producing review studies. These reviews are widely dispersed across journals rather than concentrated in a few core outlets. Systematic reviews, purpose-specific reviews, and traditional reviews are the most commonly used types. These findings have practical implications for researchers aiming to produce high-quality review studies, and for journal editors, funding agencies, and policymakers seeking to trace and support the development of this field.
