  We present preliminary results on a global study of X-ray binaries using 14
Ms of data from the Rossi X-ray Timing Explorer satellite. Our initial study on
GX 339-4 is recapped as an introduction to the methods used. We use a
consistent analysis scheme for all objects, with three different spectral
models to fit the powerlaw and disc components. We also take into account the
possibility of a line being present in the data. The resulting almost 4000
observations allow the tracking of the spectral properties of the binaries as
they evolve through an outburst. Our investigations concentrate on the disc and
line properties of the binaries when in outburst. We also show the
Disc-Fraction Luminosity diagram for the population of X-ray binaries studied
which will enable us to further links with AGN.
