In the field of orbital mechanics, this is the seminal text on the restricted three body problem. When I started graduate school, this was one of the textbooks that was invaluable to my first orbital mechanics research project. I continually refer back to this book, and I have exposed the next generation of graduate students to this valuable text. Every textbook written since Szebehely's book that covers the restricted three body problem refers back to this book. Researchers around the world would agree with me that if you are studying the restricted three body problem, Szebehely's book is a must read.
