In the past several decades, technology has had a dramatic impact on human resource management (HR) processes and practices. For example, technology, especially theWorld Wide Web, has helped modify many HR processes including human resource planning, recruitment, selection, performance management, work flow, and compensation. These new systems have enabled HR professionals to provide better service to all of their stakeholders (e.g., applicants, employees, managers), and reduced the administrative burden in the field. Despite the widespread use of these systems, there has been a surprising dearth of theory and research on the topic. As a result, the purpose of this special issue is to (a) advance theory and research on human resource management systems (HRMS) and electronic human resource management eHRM), (b) offer new directions for research on the topic, and (c) enhance the effectiveness of these systems in organizations. As a result, this article reviews the evolution of HRMS and eHRM, provides a brief overview of the existing literature, and introduces the articles in the special issue.
