A self-contained text describing recent advances in deep inelastic scattering in high energy physics. The technique originated in the experiments that led to Rutherford's discovery of the atomic nucleus. The underlying theory and formalism are outlined and particular attention is given to the detailed determination of proton structure. [Devenish and Cooper-Sarkar] have written a book whose distinction reflects this pedigree and which is a landmark ... The authors thus deserve our congratulations.
