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