This is a very traditional view of integral equations. It is a proofs book but focuses on practical facts that lead to solutions of integral equations, rather than general properties of solutions. It is traditional partly because it is so old, and partly because the author deliberately concentrates on “well established” methods (p. v). The present book is an unaltered 1985 Dover reprint of the 1957 Prentice-Hall edition.

The book focuses on practical methods but is weak on worked examples. It usually sketches how an applied problem would be set up as an integral equation and indicates the methods for solution, but does not actually solve it. There are 32 exercises in the back that do ask for solutions of integral equations or ask for properties of particular integrals, but there are no hints or solutions for these.

The first two chapters give a lot of specific information on the Volterra and Fredholm equations (including a little bit about non-linear equations). The third chapter is a little more general and deals mostly with eigenfunctions. The fourth chapter is a miscellany and deals with several less-common forms of integral equations. For the most part there’s no discussion of numerical methods, although a few examples are scattered through the book.

An even more practical introduction to integral equations is in Arfken et al., Mathematical Methods for Physicists, Chapter 21. A more modern book (that I have not seen, but that got good reviews) is Kress’s Linear Integral Equations. It uses the operator theory, functional analysis, and Sobolev spaces point of view and covers many additional variants and methods of solution.
