A self-contained introduction of the basics of presheaf-categories with detailed discussion of representable functors and the corresponding notions of limits, colimits, adjoint functors and ind-objects forms the first third of the book.
The last part merges these two threads in a discussion of sheaves in general and abelian sheaves in particular. This provides the machinery for the consideration of abelian sheaf cohomology conceptually embedded into the general notion of cohomology and higher stacks, on which the last section provides an outlook.
The organization and emphasis of the book (for instance of the category of sheaves as a localization of the category of presheaves) makes it a suitable 1-categorical preparation for the infinity-categorical discussion of sheaves in
and of triangulated categories, i.e. stable infinity-categories, in
