It is shown that, whereas S5 0014+81 is almost certainly the most luminous quasar discovered so far, its other properties are similar to those of other high-z quasars. These properties include the physical interaction between continuum and line-emitting regions. Over the observed optical bandpass, L(3500-6700 A) is estimated to be approximately 1.2 x 10 to the 48th erg/s; this is considerably brighter than the steady state output of any known quasar. It is pointed out that the equivalent width of the C IV emission is consistent with an extension of the 'Baldwin effect,' a correlation with the continuum luminosity at a wavelength of 1550 A in the rest frame. A rich Lyman 'forest' of absorption systems is positioned predominantly shortward of the strong Ly-alpha emission.
