I am currently studying Group Theory from I.N. Herstein's Topics in Algebra.However after studying about 50 pages of it I felt it lacks a bit of geometrical flavour (one of my friends described via email some time back how dihedral groups were treated in his course).He also said that Herstein's treatment is not exactly very modern though it supposedly has some good exercises.

Question: Do I need a supplement to Topics in Algebra that treats the subject in a "modern" way or do I need to change the book(I am skeptical about the second alternative I described)?I would be obliged if someone told me what to do.It seems that I am in a fix.

    I would say tat Herstin is a great algebra book, but it doesn't go very far into Group Theory. A good (but fast) text for Group Theory is that of M. Aschbacher2012-07-14

All of the books named in the comments are good choices. Probably look at as many as you can, and decide which one(s) you would like to work through.

One book not listed is Dummit & Foote's Abstract Algebra. This book is a standard intro algebra book, for both undergraduate and graduate courses. It is fairly encyclopedic, so you would have a lot to work with. I also like how in its treatment of groups emphasizes group actions, a very fruitful idea that is left out of some books, for example Gallian's Contemporary Abstract Algebra.

I first learned algebra from Herstein in Honors Algebra as an undergraduate, so the book will always have a special place in my heart. Is it old fashioned? I dunno if at this level it really makes that much of a difference. No, it doesn't have any category theory or homological algebra and no, it doesn't have a geometric flair. What it does have is the sophisticated viewpoint and enormous clarity of one of the last century's true masters of the subject and perhaps the single best set of exercises ever assembled for an undergraduate mathematics textbook. When a graduate student is scared to take his qualifier in algebra, I give him some very simple advice: I tell him to get a copy of the second edition of Herstein and to try to do all the exercises. If he can do 95 percent of them, he's ready for the exam. Period.

So to be honest, I don't think it's really necessary when you're first learning algebra to get a more "modern" take on it. It's more important to develop a strong foundation in the basics and Herstein will certainly do that. If you want to look at a book that focuses on the more geometrical aspects as a complement to Herstein at about the same level, the classic by Micheal Artin is a very good choice. (Make sure you get the second edition,the first is very poorly organized in comparison!) Another terrific book you can look at is E.B.Vinberg's A Course In Algebra, which is my single favorite reference on basic algebra. You'll find it as concrete as Artin with literally thousands of examples, and it's beautifully written and much gentler then either of the others while still building to a very high level. I think it may be just what you're looking for as a complement to Herstein.

    @Mathmagician1234 Hello i read your blog and saw tuloomath website. I must say i am really impressed with your interest. I am from non math background and entering into maths as math majors. i will be starting my graduate studies in about couple of months. i am not used to proofs in analysis and algebra. Can you suggest me books for beginner level and for self study for analysis and algebra keeping in view that i have no strong proof background. Thanks to you2016-06-11
