(Reference Request) Calculus on Banach Spaces
- For a short introduction, I suggest Ambrosetti and Prodi, A primer of nonlinear analysis, Cambridge 1995 (second edition).
- Another good source is the Springer book by Abraham, Marsden, Ratiu on Maniflds, tensor analysis and applications.
- There is something in J. T. Schwartz's book on Nonlinear functional analysis, Gordon and Breach.
- The most complete source is, as far as I know, the book by Cartan, Differential calculus, Hermann.
Anyway, you should keep in mind that differential calculus in normed spaces is rather easy and classical. Integration theory becomes more intriguing and difficult for vector-valued functions.

You're in luck-Henri Cartan's beautiful Differential Calculus has just been republished in an inexpensive paperback at Createspace. For a generation,it and it's sequel, Differential Forms, have together been considered the definitive text on calculus on Banach spaces. The latter has been available from Dover in an inexpensive paperback for over 10 years now,but without the first half of the course, it's been very difficult to use for course study because Cartan's notation is unique at this level and so it's been hard to find the prerequisites. The first half has been notoriously difficult and expensive to buy.
