Mean pulse profiles and polarization parameters at 435, 660 or 1500 MH
z obtained using the ATNF Parkes radio telescope are presented for 66
southern pulsars, About half of these pulsars were discovered in the P
arkes southern pulsar survey and most have no previously published pol
arization parameters. Where possible, beam impact parameters and incli
nation angles are computed assuming a circular beam geometry and the r
otating-vector model. Implications of the results for models of the pu
lse emission mechanism are briefly discussed.
