This is the definitive treatment of the phenomenology of galaxies--a clear and comprehensive volume that takes full account of the extraordinary recent advances in the field. The book supersedes the classic text Galactic Astronomy that James Binney wrote with Dimitri Mihalas, and complements Galactic Dynamics by Binney and Scott Tremaine. It will be invaluable to researchers and is accessible to any student who has a background in undergraduate physics.

The book draws on observations both of our own galaxy, the Milky Way, and of external galaxies. The two sources are complementary, since the former tends to be highly detailed but difficult to interpret, while the latter is typically poorer in quality but conceptually simpler to understand. Binney and Merrifield introduce all astronomical concepts necessary to understand the properties of galaxies, including coordinate systems, magnitudes and colors, the phenomenology of stars, the theory of stellar and chemical evolution, and the measurement of astronomical distances. The book's core covers the phenomenology of external galaxies, star clusters in the Milky Way, the interstellar media of external galaxies, gas in the Milky Way, the structure and kinematics of the stellar components of the Milky Way, and the kinematics of external galaxies.

Throughout, the book emphasizes the observational basis for current understanding of galactic astronomy, with references to the original literature. Offering both new information and a comprehensive view of its subject, it will be an indispensable source for professionals, as well as for graduate students and advanced undergraduates.

There are three specific areas in which this book fails. I will address them in turn: 1) The information is way out of date. Although the publishing date is recent, the authors have made very little attempt to present the major advances that have occurred in this science over the last few years. As a result of this problem, there is some critical information in the book that is simply inaccurate. The information reflects understandings that are five to ten years old - not what we know today. 2) The writing style is very difficult to follow. The authors seem to think they are writing for their fellow professional astronomers, not for students. They don't explain the concepts sufficiently and they end up leaving the reader confused and disappointed. 3) About half the pages are mostly mathematics. This is fine if you understand advanced math and you can follow the authors reasoning. The problem is that as I closely checked the math I found glaring errors in it. On just about every few pages there would be a math error. This makes it that much more difficult to understand the information. I would suggest you save your money - and frustration! Find a better book.
