Query: Multi-wavelength observations of isolated neutron stars   Forty years elapsed since the optical identification of the first isolated
neutron star (INS), the Crab pulsar. 25 INSs have been now identified in the
optical (O), near-ultraviolet (nUV), or near-infrared (nIR), hereafter UVOIR,
including rotation-powered pulsars (RPPs), magnetars, and X-ray-dim INSs
(XDINSs), while deep investigations have been carried out for compact central
objects (CCOs), Rotating RAdio transients (RRATs), and high-magnetic field
radio pulsars (HBRPs). In this review I describe the status of UVOIR
observations of INSs, their emission properties, and I present recent results.
