Because of the fast increase in the number of known quasars, we have prepared an updated version of our catalogue of quasars and active nuclei (Véron-Cetty & Véron, 1998) which now contains 13214 quasars, 462 BL Lac objects and 4428 active galaxies (of which 1711 are Seyfert 1). Like the eighth edition, it includes position and redshift as well as photometry (U, B, V) and 6 and 11 cm flux densities when available. We also give a list of all known lensed and double quasars.
