A book on the subject of normal families more than sixty years after the
publication of Montel's treatise Ler;ons sur les familles normales de
fonc- tions analytiques et leurs applications is certainly long overdue.
But, in a sense, it is almost premature, as so much contemporary work is
still being produced. To misquote Dickens, this is the best of times,
this is the worst of times. The intervening years have seen developments
on a broad front, many of which are taken up in this volume. A unified
treatment of the classical theory is also presented, with some attempt
made to preserve its classical flavour. Since its inception early this
century the notion of a normal family has played a central role in the
development of complex function theory. In fact, it is a concept lying
at the very heart of the subject, weaving a line of thought through
Picard's theorems, Schottky's theorem, and the Riemann mapping theorem,
to many modern results on meromorphic functions via the Bloch principle.
It is this latter that has provided considerable impetus over the years
to the study of normal families, and continues to serve as a guiding
hand to future work. Basically, it asserts that a family of analytic
(meromorphic) functions defined by a particular property, P, is likely
to be a normal family if an entire (meromorphic in
