Currently we are compiling a new, comprehensive sample of 14,587 broad-line AGNs at z < 0.35, which are uncovered homogeneously from the complete database of galaxies and quasars observed spectroscopically in the SDSS DR7. Careful analyses of the optical spectra, particularly in the Hα and Hβ regions, are carried out and the broad Hα emission line is used to indicate the presence of an AGN. This catalog will be made publicly online in the near future.
