This catalog is the result of combining the spectral types in 2011ApJS..193...24S (Paper I) and 2014ApJS..211...10S (Paper II), the first two major papers of the Galactic O-Star Spectroscopic Survey (GOSSS). Together they constitute Data Release 1.1 of the survey and they supersede the previous 1.0 release from June 2013. Most of the spectral types for northern ({delta}>-20{deg}) stars are from Paper I and all of the spectral types for southern ({delta}<-20{deg}) stars are from Paper II. However, for some northern stars the spectral type is from Paper II.
