The evidence for the evolution of the intergalactic clouds that produce the Lyman-alpha absorption lines in the spectra of QSOs is reviewed. The recent detection of OVI in clouds that produce both Lyman-alpha and Lyman-beta absorption lines is discussed. The identification of molecular hydrogen in the spectrum of 1442+101 (OQ172) is not confirmed by high resolution spectra.
