RESUMEN
PURPOSE: This study aims to review the last 50 years of academic research on collective leadership (CL) and how far it has progressed by using the Scopus database and the science mapping technique of bibliometric analysis. DESIGN/METHODOLOGY/APPROACH: This study has analysed 417 publications from the Scopus database on collective leadership from 1967 to 2023. Data were analysed using MS Excel and VOSviewer. FINDINGS: There has been research from different parts of the world on the various aspects of collective leadership. In recent years, collective leadership research has gained momentum. However, collective leadership is still at a nascent level when it comes to the applicability of the concepts. So far, the research on collective leadership has relied on themes such as shared leadership and distributed leadership, how collective leadership differs from other similar-looking leadership styles such as transformational leadership, and how this influences followers' outcomes such as team effectiveness, achievements, relations, commitment, etc. Most of the research so far has been done in the United States of America, the UK and the Australian context. There exists a huge gap for studying collective leadership in African, Middle Eastern and Asian contexts. RESEARCH LIMITATIONS/IMPLICATIONS: Collective leadership research trends may be addressed to enable academics and practitioners to better understand current and future trends and research directions. Future studies in this field might use the findings as a starting point to highlight the nature of the topic. ORIGINALITY/VALUE: Bibliometric techniques provide a far more comprehensive and reliable picture of the field. This article has the potential to serve as a one-stop resource for researchers and practitioners seeking information that can aid in transdisciplinary endeavours by leading them to recognized, peer-reviewed papers, journals and networks.
