The Universe became fully reionized, and observable optically, at a timecorresponding to redshift z ~ 6.5, so it is only by studying the HI andmolecular absorption lines against higher-redshift, radio-loud sources that onecan hope to make detailed studies of the earliest stages of galaxy formation.At present no targets for such studies are known. In these proceedings wedescribe a survey which is underway to find radio-loud quasars at z > 6.5, andpresent broad-band SEDs of our most promising candidates.
