Abstract: The properties of charge density wave (CDW) low dimensional conductors are reviewed, with special reference to the molybdenum bronzes. For quasi-one-dimensional materials showing non linear transport due to the depinning of the CDW, the origin of metastability in the low electric field state as well as some aspects of CDW dynamics, are discussed. Results obtained by local techniques such as EPR and proton channeling may be consistent with the creation, annihilation and motion of CDW structural defects, such as phase dislocations, under applied electrical fields or through thermal treatments. We also discuss the properties of quasi 2D CDW materials such as the purple Mo bronze, which may show SDW and magnetic field induced transitions.
