The field of ultraviolet astronomy offers unequalled scientific promise yet has not been blessed with a multitude of space missions (as has been the case for other spectral domains). This book contains a distillation of the community's views on the topic and the desires for future observational facilities. As such, it provides the most up-to-date information on the topic of ultraviolet astronomy from a very broad point of view, presenting a compilation of lectures given at a specialist meeting and combining theoretical arguments with observational reports and detailed instrumental information.
