The second LAT AGN catalog (2LAC) includes 1017 {gamma}-ray sources located at high Galactic latitudes (|b|>10{deg}) that are detected with a test statistic (TS) greater than 25 and associated statistically with AGNs. However, some of these are affected by analysis issues and some are associated with multiple AGNs. Consequently, we define a Clean Sample which includes 886 AGNs, comprising 395 BL Lacertae objects (BL Lac objects), 310 flat-spectrum radio quasars (FSRQs), 157 candidate blazars of unknown type (i.e., with broadband blazar characteristics but with no optical spectral measurement yet), 8 misaligned AGNs, 4 narrow-line Seyfert 1 (NLS1s), 10 AGNs of other types, and 2 starburst galaxies. Where possible, the blazars have been further classified based on their spectral energy distributions (SEDs) as archival radio, optical, and X-ray data permit. While almost all FSRQs have a synchrotron-peak frequency <10^14^Hz, about half of the BL Lac objects have a synchrotron-peak frequency >10^15^Hz. The 2LAC represents a significant improvement relative to the first LAT AGN catalog (1LAC), with 52% more associated sources. The full characterization of the newly detected sources will require more broadband data. Various properties, such as {gamma}-ray fluxes and photon power-law spectral indices, redshifts, {gamma}-ray luminosities, variability, and archival radio luminosities and their correlations are presented and discussed for the different blazar classes. The general trends observed in 1LAC are confirmed. 2011ApJ...743..171A https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/743/171 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to J/ApJS/199/31 : Fermi LAT second source catalog (2FGL) (Nolan+, 2012) J/A+A/535/A69 : AGN Fermi/LAT {gamma}-ray and 37GHz fluxes (Nieppola+, 2011) J/ApJ/726/16 : {gamma}-ray loud blazars (Linford+, 2011) J/ApJ/741/30 : Radio/{gamma}-ray correlation in AGN (Ackermann+, 2011) J/ApJS/194/29 : Observations of blazars at 15GHz (Richards+, 2011) J/ApJ/742/27 : 15GHz and jet properties of MOJAVE blazars (Lister+, 2011) J/ApJ/742/66 : Fermi/LAT observations of Swift/BAT active Gal (Teng+, 2011) J/ApJ/716/30 : SED of Fermi bright blazars (Abdo+, 2010) J/ApJ/718/587 : The Fermi-AT20G catalog (Mahony+, 2010) J/ApJ/722/520 : Gamma-ray light curves of Fermi blazars (Abdo+, 2010) J/ApJ/722/L7 : Fermi/LAT detected MOJAVE AGNs (Pushkarev+, 2010) J/ApJ/715/429 : First Fermi-LAT AGN catalog (1LAC) (Abdo+, 2010) J/ApJ/709/1407 : SED of the Fermi blazars (Li+, 2010) J/ApJS/188/405 : Fermi-LAT first source catalog (1FGL) (Abdo+, 2010) J/ApJ/706/L7 : The Fermi LAT sky as seen by INTEGRAL/IBIS (Ubertini+, 2009) J/ApJ/700/597 : FERMI LAT detected blazars (Abdo+, 2009) J/ApJ/654/186 : VI photometry of Cepheids in NGC 5128 (Ferrarese+, 2007) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/743/171 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/743/171 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/743/171 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/743/171 https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/743/171 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/743/171 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/ApJ/743/171/2LAC (2LAC catalog: high latitude (tables 3 and 7) and low-latitude sources ((tables 4 and 8)) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/743/171/2LAC? https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/743/171/2LAC? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/743/171/2LAC?
