Query: Bloch's principle   A heuristic principle attributed to A. Bloch says that a family of
holomorphic functions is likely to be normal if there is no nonconstant entire
functions with this property. We discuss this principle and survey recent
results that have been obtained in connection with it. We pay special attention
to properties related to exceptional values of derivatives and existence of
fixed points and periodic points, but we also discuss some other instances of
the principle.
