I’m not sure how long this has been there (a while now; I’m imporing this from an old blog of mine), but Google has added a filter on its Advanced Search page which allows you to filter search results by the license that content on a website is released under, which would be useful, for example, if you are looking for content which you can republish on your page.

If you have a website, consider joining the Money4Banners advertising network. They will pay you £10 + £5 each month for displaying a small advert on three of your pages, regardless of traffic. American webmasters are welcome, and since £10 == $20, you make more!
