I am about to start learning Algebraic Number Theory and thus was looking for some expository articles on this subject. So far I have found two such articles:

- Dickson, L. E.. (1917). Fermat's Last Theorem and the Origin and Nature of the Theory of Algebraic Numbers. Annals of Mathematics, 18(4), 161–187. http://doi.org/10.2307/2007234
- Mazur, Barry. (2008). Algebraic Numbers. has appeared as a chapter in the book The Princeton Companion for Mathematics, by Timothy Gowers, June Barrow-Green, Imre Leader (Editors), American Mathematical Society (2008). http://www.math.harvard.edu/~mazur/preprints/algebraic.numbers.April.30.pdf

I wish to read more such articles before I start solving Marcus's book. So, I will be happy to know about more such articles.
