One website, multiple libraries

That's exactly what I am searching for. As a matter of fact, I have stumbled upon this sort of website that would search the book I'm looking for at the different libraries in my city; public and college libraries alike. But alas, I didn't bookmark and after spending more time that I can spare googling I find this post to be my last resort hoping that someone might help me


I probably spend more time looking for that one website than I would have researching each database of all the libraries in NYC separately.

So, who knows what I want?
