"This impressive book gives a comprehensive account of the developments of large parts of number theory in the twentieth century. ... The result of the author's endeavours is a magnificent work of reference which contains 6849 references on 235 pages and informs its reader on all important developments within the book's scope. For anyone who is serious about number theory it will be indispensable for many years to come." (Ch. Baxa, Monatshefte fur Mathematik, Vol. 178 (1), 2015) "This is an impressive effort to provide an annotated history of a large chunk of number-theoretic research during the 20th century. This volume can serve as a useful resource to current researchers in rational number theory and as an inspiration to future generations of mathematicians. As such, it would be a worthwhile investment for any self-respecting research mathematics library." (Angel V. Kumchev, Mathematical Reviews, May, 2014) "The book is an outstanding piece of work; it contains 6849 references, as well as an author index and a subject index, and it will be an invaluable source both for mathematicians working in number theory as well as for those interested in the history of mathematics of the 20th century." (Franz Lemmermeyer, Zentralblatt MATH, Vol. 1230, 2012)
