From the reviews of the third edition:
This is the third edition of a famous work on the basics of numerical analysis. It is a well-written textbook for advanced undergraduate/beginning graduate students containing both classical methods and modern approaches to numerical mathematics. The theory is illustrated by many interesting examples, and carefully selected exercises lead the reader to a better understanding of the topics discussed. ... The third edition contains new material and several improved passages and will be useful also for those who already use the previous editions. (European Mathematical Society Newsletter, September, 2003)
This is the third edition of a textbook first published in 1980. It is intended as a comprehensive introduction to ... numerical analysis for the final year undergraduate or beginning graduate student. ... As a reference work it is clearly organized and the table of contents ... makes it easier to refer to individual sections. ... it will serve both as an invaluable reference and as a means to acquire some more theoretical background ... . (Gerry Leversha, The Mathematical Gazette, Vol. 88 (512), 2004)
Among the book's many particular features ... we would like to emphasize the excellent presentation of the following topics: fast Fourier transform methods, thorough discussion of the most important minimization methods, solution of stiff or implicit ordinary differential equations, solution of differential algebraic systems, basics of multigrid methods. ... This ... makes the present well-written book very profitable for every reader interested in or working on problems of Numerical Analysis.
