MILLIQUAS v3.3 includes data up to 6 April 2013, including SDSS-DR9. 1,246,268 objects are displayed, including 234554 QSOs from the literature (type I only), 21391 AGN (ie, Seyferts for which the integrated disk outshines the core), 1763 Bl Lacs, 912702 photometric quasars (primarily from SDSS-based NBCKDE and BOSS), and 75858 radio/X-ray associated QSO candidates. A radio and/or X-ray identification is shown where applicable, plus, for the photometric and radio/X-ray associated objects, the probability of each being a true quasar. These expected yields total to 1,124,187 quasars, making MILLIQUAS a true million-quasar catalog.
Here is the ReadMe for the catalog, which gives details, file layout and references for the source data. Appendix A of the ReadMe gives details of the photometric selection and processing.

Stars & Galaxies: Milliquas is extracted from a larger database which includes stars & galaxies which are radio/X-ray associated to a confidence of 80%+. These are presented below with the same file layouts as Milliquas. No documentation, but the citations are given in the Milliquas & ARXA ReadMe's.
The Atlas of Radio/X-ray Associations (ARXA, 2010 PASA, 27, 283) is here.
