Personal knowledge management (PKM) is a label for the effort to integrate personal information management (PIM), focused on individual skills, with knowledge management (KM). Many people undertaking this task have taken an organizational perspective. From this perspective, understanding of the field has developed in light of expanding knowledge about human cognitive capabilities and the permeability of organizational boundaries. The other approach for PKM is metacognitive - it compares various modalities within human cognition as to their competence and efficacy (Sheridan, 2008).
