From the reviews: "Walter Gautschi is one of the leading numerical analysts of the second half of the 20th and the beginning of the 21st century. ... Brezinski and Sameh have undertaken to summarize Gautschi's work in a generally accessible form ... . This multi-volume work is not only for readers who are interested in the recent history of numerical analysis, but also for those who want to gain a general overview of this vast field." (Kai Diethelm, Computing Reviews, May, 2014) "In each topic it goes in two steps: first there is a part in which well known specialists comment and summarize the contributions of Gautschi each of the topics in the volume and in a second part the papers classified in this topic follow. ... In the e-book version, the chapters are downloadable separately which is of course a highly desirable feature. Libraries will find these hard copies on their shelves to be of lasting significance." (A. Bultheel, The European Mathematical Society, December, 2013)
