The main UV resonance lines show P Cygni profiles in the first days, which change into symmetric pure emission lines, and then slowly become fainter and narrower. Lines of higher ionization species reach their peak luminosity later than those of low ionization. Description: We mainly concentrate on the analysis of the high resolution observations of V1974 Cyg (about 140 spectra), which cover 200 days and 330 days of its post-outburst evolution in the SWP and LWP cameras, respectively, at a resolution of about 25km/s. The tables contain, in a sequence, the IUE camera and image number, the date of the observation, and the measured radial velocities in km/s. The laboratory vacuum wavelengths of the transitions considered are indicated. The labels "p" and "d" refer, respectively, to the principal and the diffuse-enhanced absorption systems. Blanks mean that no reliable radial velocity measurements could be obtained.
