I to IV (Springer). Contains many interesting historical, heuristic and motivational comments. Includes several details on Bourbaki ("bande militante") in Vol. III. Great mathematical content, plus some provocative thoughts.</p>
http://mathoverflow.net/questions/21024/what-is-the-exterior-derivative-intuitively/56008#56008Answer by fcukier for What is the exterior derivative intuitively?fcukier2011-02-19T19:36:30Z2011-02-19T19:36:30Z<p>Another conceptually nice definition of the exterior derivative is given in Bourbaki (Varietes differentielles et analytiques, Fascicule de resultats), (8.3.4) and (8.3.5).
The idea is the following: if w is an exterior p-form on X, consider it as a section
w: X to Omega^p(X)
of the bundle Omega^p(X) of p-forms. It makes sense to take its derivative dw at each point x in X. Then one sees that dw corresponds to a p+1 exterior form. </p>
<p>By the way, a natural and simple definition of tangent vector on a smooth manifold is given in the same book in (5.5.1).</p>

Another one is Mumford, lectures on curves on an algebraic surface. </p>

He gives a nice proof, using the residue theorem plus basic linear algebra.</p>
