From the reviews of the second edition: "The work is clearly a labor of love. It immerses the reader in a thorough explanation of the latest data from modern ground- and space-based observatories. From Hubble's original galaxy classification system to the standard cosmological model, it is all here. This is a well-organized, well-placed, and thoroughly referenced 'golden review' of galactic formation and evolution--a must have for any serious student or scientist in the field. Summing Up: Essential. Upper-division undergraduate through professional collections." (T. D. Oswalt, CHOICE, Vol. 45 (8), 2008) "Keel explores in this book ... that the assembly of galaxies as we now see them has occurred continuously over the past 12 or 13 Gyr and can be studied in at least two ways: by looking far back, at large redshifts, and by winkling out the oldest stars surviving in the Milky Way and other nearby galaxies. ... Keel's style is conversational; indeed the book is delightfully written, and the annotations to the bibliographic items pithy and informative." (Virginia Trimble, The Observatory, Vol. 128 (1203), 2008)
