Are there any books other than Jeffrey Lee's "Manifolds and Differential Geometry" and "Heat kernels and Dirac operators" and Loring Tu's "Differential Geometry" to learn principal, associated, line and density bundles and vector-valued forms?
Jeffrey Lee's book has too many errors and the other two books are hard for me.
I have studied "Introduction to smooth manifolds" and "Riemannian manifolds" by John Lee.
