The International Conference on Calorimetry in Particle Physics has become a major forum for state-of-the-art developments of calorimetry techniques. The tenth conference was attended by about 150 physicists from 20 countries and covered all aspects of calorimetric particle detection and measurements, with emphasis on high energy physics experiments as well as experiments in nuclear physics and astrophysics. This volume of proceedings contains three parts: introductory papers, contributed papers and a summary. The introductory papers start with a historical review of the development of calorimetry technology, and continue with overviews of the status of calorimetry in high energy physics and astrophysics, which are followed by discussions on calorimetry in future accelerator facilities, such as linear colliders and the Super B Factory. A "hot" technology regarding the "energy flow concept" is also dealt with.
