To map the intellectual structure of human resource management studies in the past decade, this study investigated the most important publications and the most influential scholars as well as the correlations among these documents by analyzing 33,132 citations of 1,267 articles published by SSCI journals in human resource management area between 1996 and 2005. This study further mapped the invisible network of knowledge of human resource management using co-citation analysis. Such a mapping can help identify the paradigm shift of human resource management research, and provide a valuable tool for researchers to access the literature in this area.
