We have produced a catalogue of line identifications and equivalent width measurements for all absorption features in eight ultraviolet echelle quasar spectra. These spectra were selected as having the highest signal‐to‐noise ratio among the  Hubble Space Telescope /STIS spectra obtained with the E230M grating. We identify 56 metal‐line systems towards the eight quasars, and present plots of detected transitions, aligned in velocity space. We found that about 1/4–1/3 of the features in the Lyα forest region, redward of the incidence of the Lyβ forest, are metal lines. High‐ionization transitions are common. At the redshift range we study,   z  &lt; 1.7 , we see both O  vi  and C  iv  in 88–90 per cent of the metal‐line systems for which the spectra cover the expected wavelength. Si  iii  is seen in 58 per cent, while low‐ionization absorption in C  ii , Si  ii  and/or Al  ii  is detected in 50 per cent of the systems for which they are covered. This catalogue will facilitate future studies of the Lyα forest and of metal‐line systems of various types.
