  We discuss selection of QSO candidates from the combined SDSS and GALEX
catalogues. We discuss properties of QSOs within the combined sample, and note
uncertainties in number counts and completeness, compared with other SDSS-based
samples. We discuss colour and other properties with redshift within the sample
and the SEDs for subsets. We estimate the numbers of faint QSOs that are
classified as extended objects in the SDSS, and consequent uncertainties that
follow.
