Addresses some of the key debates within the HRD literature and considers the extent to which HRD can be described as a field of study. The paper addresses the issues raised in the contributions that make up this special issue and identifies a broad range of methodologies and use of research methods. It argues that all of the contributions fit into at least one theoretical perspective: capabilities, psychological contacts and the learning organization/organizational learning. The paper concludes with a consideration of the prescriptions which the perspectives advocate for HRD in organizations. © 2000, MCB UP Limited
