 "classic text is as fresh and useful today as when first published. Noted for the economy of its presentation, it includes a wealth of basic and key results from all parts of mathematical logic." -Solomon Feferman, Stanford University, January 2001"The book remains an excellent introduction to logic . . .  reads as a continuous whole, not a set of isolated topics . . . " -C. W. Kilmister,The Mathematical Gazette, July 2003
