" ""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"
