Assuming I have any readers at all that haven’t already done so:
Go sign the petition to the White House to
Require free access over the Internet to scientific journal articles arising from taxpayer-funded research.
You’ll need to create a whitehouse.gov account if you don’t already have one; that takes maybe 2-3 minutes (mostly waiting for verification email).
The petition was mounted Monday. It’s almost halfway to the required 25,000 signatures already. It won’t–by itself-change anything, but it couldn’t hurt.
Oh, and if you’d like to know more about open access itself, you could buy my book (from ALA Editions): Open Access: What You Need to Know Now. It’s a reasonably quick read with lots of good resources.
