Book Name: Algebra (Graduate Texts in Mathematics, Volume 211)
Author/Authors: Serge Lang
Publication Date: January 8, 2002
Publisher: Springer New York
Serge Lang’s Algebra is a comprehensive graduate-level textbook intended for a year-long course in abstract algebra, as well as a reference work for mathematicians. Originally published in 1965, the book became highly influential because it combined classical algebra with newer structural approaches. This review concerns the revised third edition of 2002, which contains additional exercises and numerous corrections.
The book begins with the fundamental objects of algebra—groups, rings, modules and polynomials—and then develops field theory, algebraic equations, Noetherian rings and modules. Later sections treat linear algebra, tensor products, representations and semisimple structures before advancing to homological algebra, including chain complexes, derived constructions and finite free resolutions. Category-theoretic language is used to reveal connections among these subjects, giving the reader a unified picture of algebra rather than presenting its branches as unrelated collections of techniques.
Lang’s exposition is concise, rigorous and remarkably broad. Definitions and major results are presented efficiently, with relatively little motivational discussion, so readers are expected to supply many intermediate details and work seriously through the exercises. This makes the book highly valuable for graduate students who already possess a solid undergraduate background, but demanding as a first introduction to abstract algebra. Its lasting significance lies in the way it helped incorporate category theory and homological algebra into the standard graduate algebra curriculum.

Key Takeaways
- The book offers a broad and unified treatment of graduate-level algebra.
- It connects classical subjects with category theory and homological algebra.
- Its concise, proof-oriented style requires mathematical maturity and active work from the reader.
- It is better suited to graduate study and reference use than to a first course in abstract algebra.
