Add to ORKGThe cosmological evolution of active galactic nuclei (AGN) luminosity function is poorly known at the faint end, since active nuclei fainter than their host galaxies cannot be selected by color techniques. A sample of low luminosity AGN candidates has been selected on the basis of their variability. We carried out spectroscopic observations with the WYFFOS multi-fiber facility at the 4.2 m William Herschel Telescope. Preliminary results are presented, indicating the validity of the selection technique
