Abstract:
    The rotation measures of 555 extragalactic radio sources are calculated
    as a result of a large number of new linear polarization measurements
    carried out by us at several wavelengths.  A summary of references for
    previous polarization measurements is included, and the procedure for
    optimizing the number of unambiguous rotation measures is described.

Note on optID: unexplained in the text, but most likely: G=galaxy, 
               N=N-galaxy, D=D-galaxy, DB=dumb-bell galaxy, 
               En=elliptical galaxy, Q=quasar, S0=S0 galaxy
               SO (=S0 ?), ED and ND are presumably intermediate types
