      It is pleasing that the first four editions of The Rheology Handbook, published in 2002, 2006, 2011 and 2014 sold out so unexpectedly quickly. It was positive to hear that the books met with approval, not only from laboratory technicians and practically oriented engineers, but also from teachers and professors of schools and colleges of applied sciences. Even at universities, The Rheology Handbook is meanwhile taken as an introductory teaching material for explaining the basics of rheology in lectures and practical courses, and as a consequence, many students worldwide are using it when writing their final paper or thesis. This textbook is also available in German language, and between 2000 and 2016 also here, five editions were published meanwhile (title: Das Rheo­logie Handbuch).

      New in this fifth edition is Chapter 13 (shear tests with powders and bulk solids). Further present-day examples have been added resulting as well from contacts to industrial users as well as from corporation with several working groups, e. g. for developing modern standardizing measuring methods for diverse industrial branches. The references and standards have been updated (e. g. in Chapter 15).

      I hope that The Rheology Handbook will prove itself a useful source of information for characterizing the above mentioned products in an application-oriented way, assuring their quality and helping to improve them wherever possible.
