After nearly half a century of dominance by NbTi, other superconducting materials are finally making their way into use for accelerator magnets. Quadrupoles using Nb3Sn will be installed as part of the luminosity upgrade for the LHC. Recently, the High Temperature Superconductors, Bi-2212 and ReBCO have been added to the list of candidate materials. But, despite the tantalizing potential for achieving dipole fields more than twice that of NbTi, there are many challenges that still need to be overcome. Interest in high field dipoles has been given a boost by new proposals to build a high-energy proton-proton collider to follow the LHC, and programs around the world are taking on the task to answer the need. After a brief review of current progress, the talk will describe the key issues facing future development and present a roadmap for moving high field accelerator magnet technology forward.
