From the reviews of the second edition:
Springer has just released the second edition of Steven Roman's Field Theory, and it continues to be one of the best graduate-level introductions to the subject out there. ... Every section of the book has a number of good exercises that would make this book excellent to use either as a textbook or to learn the material on your own. All in all, I recommend this book highly as it is a well-written expository account of a very exciting area in mathematics. (Darren Glass, The MAA Mathematical Sciences Digital Library, February, 2006)
The second edition of Roman's Field Theory ... offers a graduate course on Galois theory. ... The author's approach is mainly standard ... . the merits of such an approach would have been helpful for readers who already know some Galois theory, or for instructors who have to pick a textbook. ... The clarity of exposition and lots of exercises make this a suitable textbook for a graduate course on Galois theory. (Franz Lemmermeyer, Zentralblatt MATH, Vol. 1172, 2009)
