The book is Copyright 1965. The fact that it is still in print says a lot about it. It must be a well-regarded standard text. The preface says that the book evolved from notes for a two-term course presented by the authors to grad students at the MIT Department of Aeronautics and Astronautics.
The book contains chapters on Review of Fluid Mechanics, Constant Density Inviscid Flow, Singular Pertubation Problems, Effects of Viscosity, Thin Wing Theory, Slender Body Theory, 3D Wings in Steady Subsonic Flow, 3D Thin Wings in Steady Supersonic Flow, Supersonic Drag, Use of Flow Reversal Theorems, Interference and Nonplanar Lifting Surface Theories, Transonic Small Disturbance Flow, and Unsteady Flow.
The book looks to be a very complete and very mathematical treatment of subsonic and supersonic aerodynamics. Unfortunately, the math was well beyond what I remember from my long-ago calculus classes. It is probably a 4 to 5 star book for its target audience.
