For the past few years a co–operative programme involving astronomers at the Universities of Cambridge, Sydney and Groningen and Lick and Steward observatories has been in progress aimed in part at obtaining a complete sample of QSO's in a selected region down to given limits of optical and radio flux. The radio sample from the 408 MHz Mills Cross at Molonglo covers two declination strips each 2° wide and centred at declinations ∼11°N and ∼17°N respectively. Part of the survey has been published as the MC2 and MC3 catalogues (Sutton et al. 1974) covering the 11° strips in the R.A. interval 11h28m–01h23m and the 17° strip in the interval 13h30m–04h13m and this section is complete to a flux limit (S) of 0.45 Jy. The rest of the survey consists of an extension of the 11° strip around the rest of the sky and to a lower flux limit of about 0.15 Jy.
