Reviews

From the Foreword: 'The story of quasars and their absorption spectra accounts for just the first half of Professor Churchill's extraordinary two book set. [...] To collect all this encyclopedia of relevant knowledge [on quasars] under one assemblage has never been attempted before and is the phenomenal achievement of these two volumes. Students and experts in the field will find them an endless source of information and a much used reference text for many years to come.' Max Pettini, University of Cambridge
