Yahoo! has released a Creative Commons Web search cut of their Web search that limits itself to content that has a Creative Commons license (they basically filter their results by looking for the license codes on the indexed Web pages).
This Yahoo! Creative Commons Web search is in addition to the original beta Creative Commons Licensed Content Search on the Creative Commons site.
And the law firm marketing spin? You can limit the search to documents you can use for commercial purposes, so there may be some law firm Web site content out there you can use
