Abstract
The seventh list of the Calán-Tololo Survey is presented. It contains information for 100 southern quasars with a B magnitude in the range 16 ≤ B < 19.5; only 20 quasars are brighter than B = 18. The redshifts z of these quasars are such that for 69 objects 1.8 ≤ z < 2.4, for 11 objects 2.4 ≤ z < 3.4 and for 20 quasars z < 1.8. These quasars were found at Cerro Calán, searching objective prism plates obtained at Cerro Tololo Inter-American Observatory, 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. Only twelve of these quasars were previously known before.
