From the reviews:
This book is concerned with integral equations and inequalities that involve functions of two or more independent variables. the book is self-contained and all results are presented in an easy-to-read way, it has been written for pure and applied professional mathematicians, engineers and physicists or the like. It certainly belongs on the bookshelf of specialists in analysis but the literature used is comprehensive, accurate and very up-to-date; many of the authors own works are cited, which shows his great expertise.
