A review of the experimental searches for physics beyond the Standard Model
performed at collider facilities is presented. The emphasis is put on topi
cs of interest for future data-taking at the upgraded Tevatron p (p) over b
ar and HERA ep colliders. The status and discovery prospects for leptoquark
s, lepton flavour violation, technicolour, R-parity violating supersymmetry
, flavour-changing neutral currents, excited fermions and contact interacti
ons is discussed.
