I respect this book but I don't like reading it very much. It has great coverage of topics, but I find it very dry and tedious. Somehow it fails to convey any of the beauty or elegance of algebra. But it is encyclopedic and has a wealth of examples, so it is still well worth owning.

A much nicer book with similar scope is Rotman's Advanced Modern Algebra: http://www.amazon.com/Advanced-Algebra-Graduate-Studies-Mathematics/dp/0821847414 (be sure to get the 2nd edition, as it is a substantial improvement over the 1st). The exposition in this book is first-rate, and the proofs are generally much cleaner and less cluttered than those in Dummit and Foote.

i taught from this book and found it to have some very clear and memorable statements of results that help a student remember the main points. e.g. the statement of just when a group is a semi direct product is very clear and useful. and there were really a lot of good problems that greatly expanded the results too. but the proofs did not thrill me.

they sometimes omitted to check important details, or gave abstract proofs that were of no use in using the theorems. but algebraists much more accomplished than me in the field have used the book, e.g. Professor Parimala at Emory used it in her course, but i did not ask her opinion.

I have mixed feelings about this book. It can be quite useful as a reference and for some explanations; that I cannot deny. On the other hand, sometimes this book just seems like too much of an encyclopedia to me. It doesn't get me excited about algebra.

I would think it ideal to start with Artin and then read Lang, supplementing Lang with examples and problems from Dummit/Foote, of which there are plenty (this is probably the book's main strength).
