I read somewhere that Herstein would prepare me nicely (abstract algebra-wise) for grad studies. I don't remember where I read it and now that I was about to buy the book I found out that there two Hersteins:
Topics in Algebra (Amazon Link)
Abstract Algebra (Amazon Link)
I wanted to figure out whether one is more advanced than the other or whether one is sequel to the other.
So I looked at both TOCs on Amazon and saw that Topics in Algebra is about 100 pages longer. Then I tried to figure out which one is more advanced by comparing. But it's kind of confusing because for example in just the group theory part, in one book there is a chapter ''Factor groups'' whereas in the other book the chapter is called ''Normal subgroups and Quotient groups''.
Now I don't know much more. So my question is:
Is one of the two Hersteins a sequel to the other, that is, are they meant to be read in a particular order?
Is one of them more advanced than the other?
Is it a good idea to read both?
I cannot tell how much overlap there is.
