A Brief Review of Future Lepton-Hadron and Photon-Hadron Colliders

Options for future $lepton-proton,lepton-nucleus,\gamma -proton,\gamma -nucleus$ and FEL$\gamma -nucleus$ colliders are discussed. In the spirit of this content, we consider TESLAxHERA, LEPxLHC, $\mu$xTEVATRON, exRHIC, LinacxLHC, $\sqrt{s}=3TeV$ $\mu p$ and CLIC based colliders.
