Numbrary

The goal of the Numbrary is to be an online library for numbers. From its about page:

It's hard to locate good numbers about anything.

Here, try it yourself: How much money have the top 3 pharmaceutical firms spent on research & development over the last 5 years?

Bet that took you a while. But these numbers are all in the public record — why should it take more than a few seconds to answer the question?

You can contribute data to the site, suggest data for it to acquire and track updates via its blog.
