@JTT,
Q:Which would you use for a book, 'on' or 'in'?
A:IN, if about the content. But problems often comes up when something falls between two stools: when we talk about computer things, ON is almost always needed. So I was and am not sure. FACEBOOK is obviously a book, but I don't know any native speak using IN FACEBOOK.

I know 'advanced search' on google, but after getting results from a particular region, I can't see the number of results. How did you do that?
