            <description>The revised 3C catalogue (3CR, Bennett 1962) forms a flux-limited sample of the most radio-powerful sources in the northern hemisphere. Over the decade and a half of HST operation we have performed "snapshot" imaging from the near-IR to the near-UV of a large number of these sources. Most recently we have completed a NICMOS 1.6 micron survey of low-redshift (z less than 0.3) 3CR sources (Madrid et al. 2006, Floyd et al 2008). The fully-reduced data for all 101 sources included in those papers are presented here in numerical order.</description>
