This special issue of the Journal of Universal Computer Science (J.UCS) contains a selection of articles presented at the Fourth International Conference on Computability and Complexity in Analysis (CCA), held in Siena, Italy, June 16-18, 2007. This conference is the fourteenth event in the series of CCA annual meetings; seventy-four participants attended this years meeting and twenty-seven talks were presented. The CCA conference series promotes the study and advancement of the theory of computability and complexity over real-valued data and its application.
