Dover's Phoenix series reprints books that do not have the sales potential to be "normal" Dover books but that might still be of some interest to a smaller circle of readers. This one reprints a 1965 translation of a book first published in Russian in 1962. In a brief review published in the American Mathematical Monthly in 1965, A. Friedman described the book as an attempt 

…to present a unified approach to the study of elliptic systems consisting of two equations, two dependent and two independent variables. This approach is based upon first conceiving the solution of a problem as a minimum in some set-up, then taking a minimizaing sequence blelonging to a compact set and concluding, finally, that a convergent subsequence converges to a minimum because otherwise the limit could be modified to yield a smaller value.

He also points out that "the book is somewhat loosely written; the proofs are often sketchy or even partly omitted, although the theorems are stated precisely."
