Studies of Fragmentation Functions using e+e- Annihilation Data from   PETRA and LEP
  We present studies of the angular and momentum distributions of charged particles in hadronic final states of e+e- annihilation. Some results are derived from reanalysis of data of the JADE experiment operating at the PETRA e+e- collider at DESY from 1979 to 1986 while other data are from OPAL.
