Some representative results of observations of cataclysmic variables,
made over the whole width of the electromagnetic spectrum, are given. At the
longest wavelengths the ejecta from novae have been found to be more massive
than previously thought. X-ray to UV flux ratios are well-correlated with rates
of mass transfer, but correlations with orbital period are shown to be the result
of observational selection. I give some representative results of observations of
cataclysmic variable stars (CVs) at different energies.
