I don't think there's a formal rule on such things, but here's what I think. When you use it as a subject or a predicate of a sentence, always use "of". For example, "An overview of XX is given", "Here's an overview of XX", "This is an overview of "XX", etc. In phrases like "give an overview" or "provide/present an overview", people sometimes use "on" in the sense that a view is given "on" or "as to" something. So you might see "I'll give you an overview on the current status" and such. But it seems a safe bet to use "of" if you're not sure.

overview of Edit: After reading other comments and answers and thinking about it a little more, my theory is this: 1. If you use "overview of" you'll never be wrong. 2. "overview of" is the technically correct collocation, but "overview on" is begining to be common in some contexts. This might be an evolution occuring in the language right now. 3. In those contexts where both of/on work, "overview on" feels a bit more rigid, direct, forceful. "of" feels more general, passive, pemissive. e.g.: The boss wants an overview of our marketing project (feels like the boss just wants us to sit with him and let him know what's going on with our project) The boss wants an overview on our marketing project (feels like the boss wants a lot of detail, maybe a presentation, etc.) But note, overview of, to my ears still sounds a bit better. 4. There are situations where "overview on" simply doesn't work. E.g.: The scout brought back a map which gave the general an overview of the landscape. This reinforces my theory that the correct term really is "overview of", because it works in certain expressions where "overview on" just sounds wrong. I hope that helps! :o)

You can use on and of. When you are using "on", it is referring to one noun phrase or one whole subject as a noun like "The Center on Positive Law". You can use "of" like "NYU School of Positive Law". It means that NYU School is referring to Positive Law or the NYU School has Positive Law.
