One question of great importance to Information Systems (IS) researchers is how to effectively and efficiently move expertknowledge from researchers to practitioners. This paper identifies a novel knowledge use process – knowledge mobilization– which focuses on the process of organizing knowledge and making it ready for active service within a community. Aliterature review of knowledge management concepts including knowledge transfer, reuse, sharing, sourcing, and informationseeking suggests that knowledge mobilization is a distinct concept, distinguishable from the other concepts in the existing ISliterature. A case study of a public health-oriented network (Supercourse) provides an example of a knowledge mobilizationsystem that delivers just-in-time knowledge.
