The evolution and popularity of the Internet and computing GRID has brought the cooperative computing research discipline to the Internet, for which we coined the term Cooperative Internet Computing (CIC). This conference brings together new and different approaches to CIC.The book contains the revised version of the 12 best papers presented at the conference, listed under four categories: theories and protocols of CIC, technologies and architecture of CIC, collaborative information retrieval, and CIC applications.This collection serves as a useful resource for those interested in the research and study of CIC.
