  HERA is the only high energy electron-proton collider in the world today and
hence has unique opportunities both to probe the structure of the proton and to
search for physics beyond the Standard Model. Results are presented for
measurements of both neutral and charged current cross sections, and for
searches for exotic processes involving direct electron-quark interactions
(leptoquarks and R-parity violating SUSY), generic coupling models (contact
interactions) and exclusive final states (isolated leptons and missing PT,
single top production and pentaquarks). Exclusion limits on proposed models are
set where no deviation from Standard Model predictions are found.
