We present the discovery of three new quasars at z > 6 in ~ 1300 deg2 of Sloan Digital Sky Survey imaging data, J114816.64+525150.3 (z = 6.43), J104845.05+463718.3 (z = 6.23), and J163033.90+401209.6 (z = 6.05). The first two objects have weak Lyα emission lines; their redshifts are determined from the positions of the Lyman break. They are only accurate to ~0.05 and could be affected by the presence of broad absorption line systems. The last object has a Lyα strength more typical of lower…

Into the central 10 pc of the most distant known radio quasar - VLBI imaging observations of J1429+5447 at z = 6.21
Context. There are about 60 quasars known at redshifts z > 5.7 to date. Only three of them are detected in the radio above 1 mJy flux density at 1.4 GHz frequency. Among them, J1429+5447 (z = 6.21)
Are Two z ∼ 6 Quasars Gravitationally Lensed? ∗
Several high-z (z > 5.7) quasars have been found during the course of Sloan Digital Sky Survey. The presence of such very high-z quasars is expected to put constraints on early structure formation.

TLDR
A luminous unresolved object with a featureless optical spectrum redward of the Lyalpha forest region, discovered from Sloan Digital Sky Survey commissioning data, is either the most distant BL Lac object known to date, with very weak radio emission, or a new type of unbeamed quasar, whose broad emission line region is very weak or absent.
