**Mathematical
Logic ***by Joseph R. Shoenfield*

This classic introduction
to the main areas of mathematical logical provides the basis for a first graduate
course in the subject. It embodies the viewpoint that mathematical logic is
not a collection of vaguely related results, but a coherent method of attacking
some of the most interesting problems that face the mathematician. The author
presents the basic concepts in an unusually clear and accessible fashion.
He concentrates on what he views as the central topics of mathematical logic:
proof theory, model theory, recursion theory, axiomatic number theory, and
set theory. There are many exercises, and they provide the outline to what
amounts to a second book that goes into all topics in more depth. This book
has played a role in the education of many mature and accomplished researchers.
