The book "Mobile Information Systems" offers a comprehensive analysis of current trends and developments in the field of mobile information and communication technology. It highlights the transformative role that mobile infrastructures and mCommerce systems play in how information is utilized. The editors, Elaine Lawrence, Barbara Pernici, and John Krogstie, have created a platform to bring together researchers and practitioners engaged in the planning, analysis, design, and implementation of mobile information systems. By discussing the differences and similarities between mobile and traditional information systems, as well as examining the organizational impacts of mobile systems, a deep understanding of the challenges and opportunities in this dynamic field is conveyed. The MOBIS conference, held in Oslo in 2004, served as an important milestone for the exchange of ideas and findings in mobile information systems research.
