A new determination of the upper limit to the cosmic diffuse background radiation, at ~110 nm, of 300 photons s -1 cm -2 sr -1 nm -1 is placed in the context of diffuse background measurements across the entire electromagnetic spectrum, including new optical, infrared, visible, and gamma-ray background measurements. The possibility that observed excess diffuse visible radiation is due to redshifted cosmological Lyα recombination radiation is explored. Also, a new standard of units for the display of spectra is advocated.
