Thanks ! Can you tell me how the fibre of a bundle is a limit in the general sense of category theory ? Idon"t understand this sentence : it is just the pullback of the bundle along the inclusion of a point. Thanks a lot.

comment Difference between a stalk of a sheaf and a fiber of a vector bundle
Thank you very much @Zhen Lin. Can you tell me please, if it's true that the fiber $ E_x = \pi^{-1} ( x ) $ of a vector bundle $ \pi : E \to X $ can be defined as the direct limit of maps $ U \to E_{U} = \pi^{-1} ( U ) $ like the stalk of a sheaf $ \mathcal{F}_x $ ? In this case, what is the direct system which define this direct limit ? Thanks a lot.
