Advice on self study of category theory I'm very intrested in start to study category theory with aim to use this in algebraic geometry. I already took courses (besides the basics) on commutative algebra and general topology with a soft introduction to algebraic topology. But I don't know any references in category theory. Can someone give some idea for what book or lecture notes I can get a introduction on this topic? 
Thank you so much in any advance!

I think the best way to learn the basics of category theory is to see it in action. For this reason, I recommend Rotman's An Introduction to Homological Algebra, but you have to be algebra-inclined.
