This survey selects both normal and obscured AGNs closely matched in luminosity across a wide range, from Seyfert galaxies with bolometric luminosities L _bol_~10^10^L_{sun}_ to highly luminous quasars (L_bol_~10^14^L_{sun}_), all with redshifts ranging from 0 to 4.3. Samples of candidate AGNs were selected with mid-infrared color cuts at several different 24{mu}m flux density limits to ensure a range of luminosities at a given redshift. The survey consists of 786 candidate AGNs and quasars, of which 672 have spectroscopic redshifts and classifications. Of these, 137 (20%) are type 1 AGNs with blue continua, 294 (44%) are type 2 objects with extinctions A_V_>~5 toward their AGNs, 96 (14%) are AGNs with lower extinctions (A_V_~1), and 145 (22%) have redshifts, but no clear signs of AGN activity in their spectra. Of the survey objects 50% have L_bol_>10^12^L_{sun}_, in the quasar regime. We present composite spectra for type 2 quasars and objects with no signs of AGN activity in their spectra. We also discuss the mid-infrared - emission-line luminosity correlation and present the results of cross correlations with serendipitous X-ray and radio sources.2013ApJS..208...24Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/208/24CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)VII/259 : 6dF galaxy survey final redshift release (Jones+, 2009)II/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)II/290 : SWIRE Photometric Redshift Catalogue (Rowan-Robinson+, 2008)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)II/255 : SWIRE ELAIS N1 Source Catalogs (Surace+, 2004)VII/250 : The 2dF Galaxy Redshift Survey (2dFGRS) (2dFGRS Team, 1998-2003)VII/203 : Las Campanas Redshift Survey (Shectman+ 1996)VII/155 : Third Reference Cat. of Bright Galaxies (RC3) (de Vaucouleurs+ 1991)J/MNRAS/421/3060 : Subaru/XMM Deep Field radio imaging.
