مقدمه و محتوای کتاب به شرح زیر است:

Introduction: I wrote these notes for my math 453 class since I couldn’t find a book that covered basic abstract algebra with the level and emphasis that I wanted. Rather than spending a lot of time on axiomatics and serious theorem proving, I wanted to spend more time with examples, simple applications and with making scenic detours. I may have gotten a bit carried away with the detours, and certainly there is more here than can be covered in a semester at a reasonable pace. However, a lot of these side topics (which I marked with a star) can be skipped to save time. In order to try to encourage students to play around with examples, I tried to include some Maple code now and then. But its role is secondary and it can be ignored without losing too much. Also since I wanted to emphasize the mathematics rather than the algorithms, I didn’t go out of my way to implement these things efficiently.
