Difference between a CS & IT degree

What's the big difference between a Computer Science and an Information Technology degree?

I was waiting for a friend in a bookstore. I still had half an hour (I like to arrive early), so I decided to Think in Sepples. I couldn't find the book, but my eyes noticed two other interesting ones: a bigass L^AT_EX book and ``Scalable Websites'' or something with a fucking fish on it. I reached for the latter.
