A FORTRAN package containing two sets of polarized NLO parton
densities corresponding to positive and sign changing gluon
densities are presented in MS-bar scheme. The sets of PDFs
are obtained from an NLO QCD analysis of the world polarized
inclusive DIS data including the recent very precise JLab CLAS data.
