Obvious targets for Extremely Large Telescopes are high-redshift galaxies and galaxy (proto-)clusters. However, due to the extremely small field-of-view of such telescopes, finding such objects, notably the rarer proto-clusters, is best be done using other facilities. The very helpful negative K-correction experienced in the far-IR to mm wavebands makes surveys in these wavebands the ideal pathfinders for high-z ELT targets.
