We identify 938 WDMS binaries within the data releases (DR) 9-12 of SDSS plus 40 objects from DR 1-8 that we missed in our previous works, 646 of which are new. The total number of spectroscopic SDSS WDMS binaries increases to 3294. This is by far the largest and most homogeneous sample of compact binaries currently available. We use a decomposition/fitting routine to derive the stellar parameters of all systems identified here (white dwarf effective temperatures, surface gravities and masses, and secondary star spectral types). The analysis of the corresponding stellar parameter distributions shows that the SDSS WDMS binary population is seriously affected by selection effects. We also measure the Na I λλ 8183.27, 8194.81 absorption doublet and H α emission radial velocities (RV) from all SDSS WDMS binary spectra identified in this work. 98 objects are found to display RV variations, 62 of which are new. The RV data are sufficient enough to estimate the orbital periods of three close binaries. Description: In this work, we search for WDMS binaries within the spectroscopic data base of the SDSS III, i.e. the ninth (SDSS-III Collaboration et al. 2014ApJS..211...17A), tenth (Ahn et al. 2014ApJS..211...17A), eleventh and twelfth (Alam et al. 2015ApJS..219...12A) DRs of the SDSS. In particular, we mined the optical (R∼2000) spectra obtained by the Sloan Exploration of Galactic Understanding and Evolution 2 survey (SEGUE-2; Rockosi et al., in preparation) and the Baryon Oscillation Spectroscopic Survey (BOSS; Dawson et al. 2013AJ....145...10D).
