Acknowledgements 1. Introduction 2.Where it all started: Post's problem and ^-completeness 3. The structure inside single degrees 4. The structure of m-degrees 5.The structure of 1-degrees 6.The structure of //-degrees 7. Elementary equivalence and undecidability 8.Where we end: variations on the theme of ^-reductibility Acknowledgements.During the writing of the first draft I have been helped in many ways by Carl Jockusch, Jr., who patiently explained to me an incredible number of results on these and other topics.R. Shore and R. Soare have extensively commented on it and given many suggestions for the Introduction.Sincere thanks to them.
