The university library is a great place to strike up a conversation. Look at the books he picks up, then start a conversation. From there, you could say something like, "I'm heading over to such-and-such for a coffee and a bagel, and I'd love to hear more about the subject/book. Care to join me?" It's non-threatening, and gives you both something to discuss.
DON'T DON'T DON'T leap in to telling him all about your feelings, at least not yet. That's sure to give him the heebie-jeebies (technical term for what happens when a guy is confronted by that icky "feelings" stuff too soon in a relatinship

).
Good luck, and keep us posted!
