Senators Support Open-Access Measure

From the Chronicle's Wired Campus article, October 2007The Senate passed HR 3043. The measure included language requiring all researchers supported by the National Institutes of Health to submit their final manuscripts to a free online archive:

The Director of the National Institutes of Health shall require that all investigators funded by the NIH submit or have submitted for them to the National Library of Medicine’s PubMed Central an electronic version of their final, peer-reviewed manuscripts upon acceptance for publication to be made publicly available no later than 12 months after the official date of publication: Provided, that the NIH shall implement the public access policy in a manner consistent with copyright law.

The Open-Access Movement is important to all and I believe it's a movement in which librarians should be major advocates. How might we go about furthering this movement within our institutions? What about open-access of all scholarly research?
