Google offers CC-filtered searching

Google's advanced search page now lets users filter results by the re-use rights allowed by Creative Commons licenses. There are three new options:
    Return results that

  1. "aren't filtered by license" (the default)
  2. "allow some forms of re-use"
  3. "can be freely modified, adapted, or built upon"
Mia Garlick's posting on the Creative Commons blog includes this comment from Lawrence Lessig: "Creative Commons is thrilled by Google’s decision to join Yahoo! in enabling the spread of CC-licensed content. Now two major search engines recognize Creative Commons licenses; this confirms that CC is an important part of the infrastructure of the Internet."

There are now three search engines that detect and make use of machine-readable CC licenses: the new Google advanced search, Yahoo's dedicated CC search engine (and the the CC option on Yahoo's regular search engine), and CC's own search engine.

(PS: I repeat my comment from March 2005, when Yahoo first offered CC-filtered searching: "All search engines can offer this service and undoubtedly more and more of them will. As copyright locks down more content more tightly, searchers will want re-use rights almost as much as relevance. Search engines that find both will have an advantage. Conversely, authors and publishers who consent to grant more reuse rights than fair-use alone already provides should make their consent machine-readable for the next generation of search engines.")
