Scientific paper

A composite low-resolution QSO spectrum derived from the observation of 402 QSOs in the Durham/AAT survey is presented. It is hoped that it will be useful as a 'reference' spectrum in the identification of weak emission features in low signal-to-noise QSO spectra. Line intensities relative to the continuum are presented for 19 emission features with rest wavelengths in the range 1075-3550 A.
