Noting the general paucity of ethical considerations in Knowledge Management (KM) research, this research commentary articulates the relevance of ethics to KM. Drawing from the classical ethical theories in philosophy, it revisits certain research focuses raised in Alavi and Leidner's (2001) well-known paper on KM and generates corresponding ethically-informed research questions. The main aim of this paper is to further KM research through such ethically-informed research questions that can be investigated by future studies. Other contributions and implications are also discussed.
