Quote from press release:
“The Creative Commons search engine helps companies, educators, and artists find content they can re-use without having to call a lawyer, and it offers authors and artists who want to share their work a competitive advantage toward having their work discovered online,” said Neeru Paharia, assistant director of Creative Commons and the search engine’s product manager. For example, a documentary filmmaker could use the Creative Commons engine to search for “images of the Eiffel Tower free for noncommercial use,” and incorporate any or all of the many photographs indexed. A DJ seeking songs free to remix or mash-up could browse listings of MP3s by their legal terms. An entrepreneur seeking illustrations for her slideshow presentation could reduce costs and liability by using a Creative Commons image-specific search. An educator building course materials could include texts and videos found by the engine. What distinguishes the Creative Commons engine from other search services is that all of the above are possible without the hassle of rights-clearance, licensing requests, or royalty payments.
The search engine was developed with the help of Nutch.org, an open-source search developer and is included in Firefox 1.0.
