The book is recommended for those who want a clear bridge between the abstract statements of global class field theory and worked consequences; its single biggest reason to buy is the combination of a rigorous presentation of the reciprocity map with numerous detailed illustrations that show how to apply existence theorems in practice. This corrected second printing improves many technical points, making the exposition more reliable for study and reference.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConcise exposition:\u003c\/strong\u003e The text presents the functorial properties of the reciprocity map in a focused way that clarifies the structure of global class field theory.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePractical illustrations:\u003c\/strong\u003e Detailed studies of classical subjects show concrete consequences of the existence theorem and how to use results in computations and proofs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrected second printing:\u003c\/strong\u003e Revisions throughout the book improve accuracy and clarity, reducing common gaps found in earlier editions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTheoretical depth:\u003c\/strong\u003e Coverage emphasizes the major achievements of algebraic number theory while keeping the chain of implications transparent for the reader.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference value:\u003c\/strong\u003e The combination of theory and practice makes the book a useful reference for researchers returning to class field theory arguments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe primary audience is graduate students and researchers in algebraic number theory who already have background in algebraic structures and want a focused treatment of global class field theory that emphasizes the reciprocity map and the existence theorem.
