Serious math learners will be thrilled by the rigorous conciseness of this textbook. Dense with information on every page and presented in a relaxed, open manner, Dummit and Foote’s Abstract Algebra effectively works to usher the reader into a realm of sophisticated algebraic concepts and theories. It seamlessly bridges any gap between graduate and undergraduate studies. The book is chock-full of clear examples and succinct proofs, making it evident that the authors have no intention of keeping the reader on a particular topic any longer than is necessary. With countless exercises and examples, Abstract Algebra proves to be an invaluable tool that is undeniably worth the price.

Introduction to Algorithms is a distinctly theoretical but all-around comprehensive book. Its use is not only limited to those taking algorithms courses but can also be utilized by anyone as an extensive reference source. Readers will learn quintessential algorithms as well as concepts such as what makes an algorithm efficient and why. Students will need a bit of mathematical background to get from cover to cover, however those who are able to do so will be intrigued by the content depth and wide spectrum of topics covered. These topics run the gamut from classical algorithms to computational geometry.

Tenacious students in favor of stimulating study will love this book. Spivak’s prose is almost charming in the way that it thrusts readers into a challenge that advanced learners will be happy to take on. He forces them to rely on their own perspicacity and reason instead of a collection of random techniques and mechanics. Sophisticated readers will appreciate the style he uses to communicate and teach calculus while others may first want to opt for a more elementary text before attempting to penetrate the solidity of Spivak’s. This fourth edition includes additional problems and other minor changes not included in the third.
