Most known galaxies at high redshifts have been found by concentrating on ultra steep spectrum (α≳l) sources in low frequency radio surveys (eg. Rottgering et al., 1994; McCarthy et al., 1990). We have been carrying out a systematic study of a large and complete sample from the 408 MHz Molonglo Reference Catalogue which is not biased by any spectral index criterion. Containing 558 sources, defined by S408 ≥ 0.95 Jy; −30° < δ < −20° and the RA ranges of 20h 20m to 06h00m and 09h20m to 14h00m, our sample is about 3 times larger in size and 5 times deeper in flux density than the well studied 3CRR sample.
