Open College Textbook Act of 2009
Congress finds the following:
(1) The growth of the Internet has enabled the creation and sharing of open content, including open educational resources.
(2) The President has proposed a new, significant Federal investment in the creation of online open-source courses for community colleges that will make learning more accessible, adaptable, and affordable for students.

Really interesting stuff and very nice to see the government thinking a bit outside the box in terms of what "open source" really means. Openness is important for far more than software.
