This paper aims to explore the potential of personal information management (PIM) and reference management. The contribution focuses on collaboration: the issues that need to be addressed in planning, the human component in collaborative information seeking, and issues for research by librarians. The paper is written against the background of research from information behaviour, PIM, collaborative information seeking and collaborative work. There is growing emphasis on collaboration in information seeking, learning and work. PIM and reference management practices and their supporting software can greatly support this. There are, however, many planning/conceptual issues as well as the human component to recon with. Although much has been published on developments in PIM and reference management, there is limited coverage of collaboration and PIM and reference management.
