The catalog was built from Sloan Digital Sky Survey Data Release Four (SDSS DR4, Cat. II/267) quasar spectra. Currently, the catalog contains ~17000 measured Mg II doublets. We also present data on the ~44600 quasar spectra which were searched to construct the catalog, including redshift and magnitude information, continuum-normalized spectra, and corresponding arrays of redshift-dependent minimum rest equivalent widths detectable at our confidence threshold. The catalog is available online. A careful second search of 500 random spectra indicated that, for every 100 spectra searched, approximately one significant Mg II system was accidentally rejected. Current plans to expand the catalog beyond DR4 quasars are discussed. Many Mg II absorbers are known to be associated with galaxies. Therefore, the combination of large size and well understood statistics makes this catalog ideal for precision studies of the low-ionization and neutral gas regions associated with galaxies at low to moderate redshift. An analysis of the statistics of Mg II absorbers using this catalog will be presented in a subsequent paper. 2011AJ....141..137Q https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/141/137 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to II/267 : The SDSS Photometric Catalog, Release 4 J/AJ/106/848 : QSO MgII absorption line systems (Drinkwater+, 1993) J/MNRAS/354/L25 : MgII absorbers in SDSS QSOs (Bouche+, 2004) J/ApJ/639/766 : SDSS-DR3 strong MgII absorbers (Prochter+, 2006) J/MNRAS/371/495 : Catalogue of 1806 MgII absorbers from SDSS DR3 J/ApJ/660/1093 : Weak MgII absorbers at 0.4<z<2.4 (Narayanan+, 2007) J/ApJ/679/239 : Associated MgII absorbers (Vanden+, 2008) J/AJ/141/137 : Pittsburgh SDSS Mg II QSO catalog (Quider+, 2011) J/ApJ/748/131 : MgII absorbers in SDSS-DR7 quasar catalog (Shen+, 2012) J/ApJ/779/161 : MgII absorbers in 0.4<z<2.3 SDSS QSOs (Seyffert+, 2013) J/ApJS/235/11 : Absorption features in SDSS.
