QCD at HERA

The book provides a review of the hadronic final state measurements at HERA in deep inelastic scattering. It covers general event properties, particle spectra, heavy flavours, jets, event shape measurements, QCD instantons and small-x physics. The emphasis is on experimental results, providing quick access to the data (complete up to fall 1997) for reference. The results are discussed in the context of QCD.
