Any word on volume III of "Sketches of an Elephant"?
Oxford University Press only indicates that the 3rd volume will be published "sometime after 2007". The nLab doesn't make any mention of when the third volume might appear. Does anyone have insider knowledge on this?

God, that stuff looks so incredibly interesting to me, but I just can't seem to break into it. I read the first chapter of Mac Lane and Moerdijk, but figured if I was struggling as much as I was with some of the basic categorical stuff I'd have no hope of getting deep into it without more work on learning category theory.
Read the first four chapters of CWM (and eventually the chapter on monads, but they don't use those until Chapter IV). The first two chapters of Mac Lane-Moerdijk are the hardest to get through; everything after that is just generalizing the results of Chapter II to fancier contexts. Also, you get more comfortable with the categorical stuff as you go; despite having studied CT for 2.5 years prior, I don't think I really understood pullbacks and other ideas until I was using them constantly while working through Mac Lane-Moerdijk.
YouTube user mimrir also has some good videos on this topic (though he seems to have stopped posting, sadly):
