5 Final remarks

The QSOs in Table 3 are in no respect, neither redshift nor brightness, a complete sample. They represent a further preliminary list of bright QSOs for which low resolution follow-up spectroscopy has been completed. Publication at this stage appears appropriate since in particular the bright high-redshift QSOs are potential targets for present (HST) and future (FUSE) space missions as well as for high-resolution spectroscopy from the ground.
