Description:
    Results are presented of deep identifications of 40 steep spectrum
    radio sources detected on RATAN-600 in an area ~100deg in the 'Kholod'
    experiment and then studied using the VLA. Candidates for optical
    objects responsible for the radio emission were found for 32 sources.
    With the exception of a few quasars and objects with ill-defined
    morphology, a large fraction of the radio sources are associated
    either with gE galaxies or with galaxies of an unknown nature.
