Yes Austin Library has a quite extensive research center. And unfortunately some sites are exploiting their openness and, can you believe it, posting their logins on blogs like http://ezproxy.free-webmaster-resources.org/2010/12/page/2/ . Oh, the audacity!
Of course I don't support such sites in the least.
password2password dot eamped dot com also offers the same feature as well as a subforum specifically for article requests. It makes sense to have an account there. 55face dot blogspot dot com too posts occasional passwords to library sites. It makes sense to bookmark it too. Of course, the best option would be to use your local library itself..
