This text contains the proceedings of the International Workshop "Visual Binary Stars: Formation, Dynamics and Evolutionary Tracks" held in Santiago de Compostela, Spain, July 29-August 1, 1997. The most recent observational results on visual double stars, as well as on their dynamics, were presented at the Workshop which had nearly 70 participants from 19 countries. Both the astrophysical data and the dynamics of visual binary stars are discussed as a background to tracing their formation and evolutionary trends, largely supported by observational results including those obtained from satellites. The book should be of interest to astronomers interested in research in both visual double and multiple star and celestial mechanics.
