Topos theory is the part of category theory that studies categories which are toposes. This includes in particular Grothendieck toposes, i.e. categories of sheaves.
There are always two ways to think of topos theory: as being

Introducing even category theory from the scratch while still managing to cover considerable ground, the following textbook is the royal road to topos theory for people with some background in first-order logic:
