An algebraic number ﬁeld is a ﬁnite extension of Q; an algebraic number is an element of an algebraic number ﬁeld. Algebraic number theory studies the arithmetic of algebraic number ﬁelds — the ring of integers in the number ﬁeld, the ideals and units in the ring of integers, the extent to which unique factorization holds, and so on.

It doesn't cover as much material as many of the books mentioned here, but has the advantages of being only 100 pages or so and being published by dover (so that it costs only a few dollars).

### Is Lang's algebraic number theory a good book?

It is not for beginners into algebraic number theory since Lang assumes his readers to know concepts and theories covered in more basic books. However, it is great for students who have taken a course in alg number theory to decide their direction of interest in the field. The book is thin and light but it is not a light reading.

### What is algebraic number theory?

Algebraic number theory studies the arithmetic of algebraic number ﬁelds — the ring of integers in the number ﬁeld, the ideals and units in the ring of integers, the extent to which unique factorization holds, and so on.

### What is the best book to start learning about number theory?

Marcus's Number Fields is a good intro book, but it's not in LaTeX, so it looks ugly. Also doesn't do any local (p-adic) theory, so you should pair it with Gouvêa's excellent intro p-adic book and you have a great first course in algebraic number theory.

### Does Neukirch's number theory use cohomology?

[Neukirch] Neukirch, Algebraic Number Theory. A very extensive and geometric approach to algebraic number theory. It even contains what is essentially the 1-dimensional case of Arakelov Theory. The treatment of class field theory, known as "Abstract Class Field Theory", is due to Neukirch himself. It does not use cohomology.
