  Many of the present and planned polarization experiments are focusing on
determination of the polarized glue. There is a comparable set of spin
experiments which can help to extract information on the separate
flavor-dependent polarized distributions. This talk will discuss possible sets
of experiments, some of which are planned at BNL, CERN, DESY and JHF, which can
be used to determine these distributions. Comments will include the estimated
degree to which these distributions can be accurately found.
