The efficient management of knowledge has become imperative for almost all types of organizations. Many approaches exist for dealing with knowledge management at a corporate level. But there is also a need to support knowledge management also at an individual level, a level which takes the specific needs, experiences and skills of knowledge workers into account. While largely unexplored within the field of knowledge management, in the field of digital libraries advanced personalization and customization concepts exist. Within this context, this paper examines these concepts and how they can be exploited to address the challenges which are typical for knowledge management. As the paper will show, many synergies exist, if knowledge management at an individual level is dealt with in combination with personal digital libraries.
