"This book is a masterly treatment by four authors with many decades of experience of SAXS and SANS and who are from world class synchrotron X-ray and neutron research facilities. From the basics and on through the instrumentation and data analysis descriptions, as well as numerous research themes and examples, this book will be invaluable to newcomers and be useful to the specialists. It also should be read in detail by structural biology researchers whether principally from crystallography, bio NMR, EM or bioinformatics. It's surely going to be a classic book." -- John Helliwell, University of Manchester
