The present edition of this book, five years after the first edition, has been spiced with several recent results which fit naturally in the point of view that had been adapted in the original text and with some new examples and constructions that will help the reader to appreciate better our approach to integrable systems. On this occasion I wish to thank my collaborators from the last five years, to wit Christina Birkenhake, Peter Bneken, t~ui Fernandes, Masoto Kimura, Vadim Kuznetsov, Marco Pedroni, Michael Penkava, Luis Piovan and Claude Roger for a fruitful interaction and for their warm friendship. Most of the results that have been added are taken from, or are inspired by, joint work with some of them; I acknowledge their permission to add these, sometimes unpublished, results. The colleagues at my newest working environment, the University of Poitiers (France), created for me a pleasant and stimulating working environment. I wish to acknowledge the support of all of them. Special thanks go to Marc van Leeuwen, Claude Quitt4 and Patrice Tanvel for sharing their insights with me, which usually led to a real improvement of parts of the text. Last but not least, Yvette Kosmann-Schwarzbach, who was not acknowledged in the first version of this book - - most probably because my gratitude to her was too big and too obvious! - - is thanked here in all possible superlatives, for her constant support and for her sincere friendship. Merci Yvette!
