The phenomenon of scattering was, and still is, split between fields of science that have little to do with each other, on a day to day basis. At one extreme is the scattering studied in high energy and nuclear physics. The distances at which the interactions occur can be measured in fermis (10**-15 meters) or less. And the interaction energies can go over an MeV. Needless to say, the technologies developed to study this in particle accelerators and nuclear reactors are quite specialized. The books give detailed treatment of this.

Off to another side is the scattering in classical electromagnetism. Nowadays, this is heavily used in engineering. For example, in antenna design in every region of the electromagnetic spectrum. Due if nothing else to the technological importance of this field, the books also treat it extensively.

Yet another type of scattering covered in the volumes is acoustic scattering. Useful in sonar, ie. underwater, and especially military applications. But also used in more prosaic applications like designing musical devices or directional microphones.

It is rare to see all such covered together well in just 2 volumes.
