About the Author
David C. Lay holds a B.A. from Aurora University (Illinois), and an M.A. and Ph.D. from the University of California at Los Angeles. Lay has been an educator and research mathematician since 1966, mostly at the University of Maryland, College Park. He has also served as a visiting professor at the University of Amsterdam, the Free University in Amsterdam, and the University of Kaiserslautern, Germany. He has over 30 research articles published in functional analysis and linear algebra.
As a founding member of the NSF-sponsored Linear Algebra Curriculum Study Group, Lay has been a leader in the current movement to modernize the linear algebra curriculum. Lay is also co-author of several mathematics texts, including Introduction to Functional Analysis, with Angus E. Taylor, Calculus and Its Applications, with L.J. Goldstein and D.I. Schneider, and Linear Algebra Gems-Assets for Undergraduate Mathematics, with D. Carlson, C.R. Johnson, and A.D. Porter.
A top-notch educator, Professor Lay has received four university awards for teaching excellence, including, in 1996, the title of Distinguished Scholar-Teacher of the University of Maryland. In 1994, he was given one of the Mathematical Association of America's Awards for Distinguished College or Unviersity Teaching of Mathematics. He has been elected by the university students to membership in Alpha Lambda Delta National Scholastic Honor Society and Golden Key National Honor Society. In 1989, Aurora University conferred on him the Outstanding Alumnus award. Lay is a member of the American Mathematical Society, the Canadian Mathematical Society, the International Linear Algebra Society, the Mathematical Association of America, Sigma Xi, and the Society for Industrial and Applied Mathematics. Since 1992, he has served several terms on the national board of the Association of Christians in the Mathematical Sciences.

The reason I am giving three stars is that my purchase was misleading. I thought the study guide photo was just a mistake in the amazon description, but that is actually what one is getting, so please be aware unlike me.
The study guide is actually pretty good though. It looks like it has example problems to most odd problems and descriptions of theory/process behind the solutions. There are pictures, words, and also paragraphs on how to use matlab for linear algebra.
It has some theory for each chapter, but not in comparison to the actual book.
Lay's text, Linear Algebra and its Applications, provides an excellent balance amongst theory and application, providing many illustrations and practice problems to ensure a reasonable understanding of linear algebra. His lessons rarely leave the reader lost, as the author scatters example problems throughout each chapter. Before reading this text, I did not understand or even fathom all the applications that one could use linear algebra for.
It's not a terribly thick book, and nor does it weigh too much, thus making it easily accessible and movable. The binding is of strong and sturdy quality.
While the CD-Rom complements the book well and provides extra commentary and practice, I did not find it necessary. The book did a wonderful job of teaching me linear algebra on its own merits.
So, should you buy this book? I'd say yes, because you probably won't be disappointed. I can't give any reason to doubt this book's quality.
Hope this review helps you- please comment with any questions or concerns.
Gil Strang's book is very well regarded, and I like it, too. However, as a writer, Strang tries a little too hard to be friendly and colloquial. As a result, some of his explanations are less clear than they need to be. It helps that videos of his linear algebra lectures are on the Web at [...], and those lectures clarify some of the "folksy" wording in the textbook. Strang obviously loves his subject and knows it thoroughly, but those qualities, however admirable, do not substitute for clear writing.
Georgi E. Shilov's book is also highly regarded, by me as well. Shilov is one of those no-nonsense Russian mathematicians who's all about the subject and doesn't care if you like him or not. As a result, his writing is very clear and straightforward, albeit a little stiff and formal even in translation. The great virtues of Shilov's book are that the writing is clear and it's very rigorous: in fact, a reader would do well to have some familiarity with abstract algebra before starting it. But the book's virtues are also its weakness: because of the rigorous treatment, Shilov offers considerably less conceptual hand-holding than Strang. Yes, you can understand what he's talking about, but you'd sure better have a strong mathematical background, time, and self-confidence to plow through his book, especially if it's on your own.
Which brings us, finally, to the Lay book. I am delighted to report that Lay combines the informal, encouraging tone and conceptual hand-holding of the Strang book with the clarity of the Shilov book. In other words, they're all good, but for most undergraduates, Lay is the best of the three. There's also an excellent study guide (Linear Algebra and Its Applications: Study Guide (update))for the Lay book.
Keep in mind that linear algebra in general has a lot of similar terms that you must memorize and understand their differences. So it is a time intensive course. At least for my class.
