  Charge and spin stripe order is a type of electronic crystal observed in
certain layered cuprates associated with high-temperature superconductivity.
Quantum-disordered stripes could be relevant for understanding the
superconductivity. Here I discuss recent experimental characterizations of the
stripe-ordered state in La(1.875)Ba(0.125)CuO(4), and compare them with
properties of superconducting compositions.
