From the reviews:
Details on ... braid groups are carefully provided by Kassel and Turaev's text Braid Groups. ... Braid Groups is very well written. The proofs are detailed, clear, and complete. ... The text is to be praised for its level of detail. ... For people ... who want to understand current research in braid group related areas, Braid Groups is an excellent, in fact indispensable, text. (Scott Taylor, The Mathematical Association of America, October, 2008)
This is a very useful, carefully written book that will bring the reader up to date with some of the recent important advances in the study of the braid groups and their generalizations. It continues the tradition of these high quality graduate texts in mathematics. The book could easily be used as a text for a year course on braid groups for graduate students, one advantage being that the chapters are largely independent of each other. (Stephen P. Humphries, Mathematical Reviews, Issue 2009 e)
This book is a comprehensive introduction to the theory of braid groups. Assuming only a basic knowledge of topology and algebra, it is intended mainly for graduate and postdoctoral students. (Hirokazu Nishimura, Zentralblatt MATH, Vol. 1208, 2011)
The book of Kassel and Turaev is a textbook ... for graduate students and researchers. As such, it covers the basic material on braids, knots, and links ... at a level which requires minimal background, yet moves rapidly to non-trivial topics. ... It is a carefully planned and well-written book; the authors are true experts, and it fills a gap. ... it will have many readers. (Joan S. Birman, Bulletin of the American Mathematical Society, Vol. 48 (1), January, 2011)
