The sixth list of the Calán-Tololo Survey is presented. It contains information for 100 new southern quasars. The objects have a B magnitude in the range 16 ≤ B < 20; for 81 objects 17.5 ≤ B < 19. The redshifts z of these quasars are such that for 53 objects 1.8 ≤ z < 2.4, for 20 objects 2.4 ≤ z < 3.4 and for 27 quasars z < 1.8. These quasars were found at Cerro Calan, searching objective prism plates taken at Cerro Tololo using the Curtis-Schmidt telescope, the thin UV prism and IIIaJ plates. Identification charts, equatorial coordinates, an estimated blue magnitude, B, and a preliminary redshift for every object are presented. All quasars in this list have been confirmed using slit spectroscopy.
