Librarians facing budget cutbacks should check out these science resources available on the internet—and usually for free—recommended by Barry Brown, science librarian, and Paul Piper, reference librarian, who say the depth of information, from journal articles to gray literature, on the open web these days is quite impressive.
The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
I recommend the OA tracking project (OATP) as the best way to stay on top of new OA developments. You can read the OATP feed on a blog-like web page or subscribe to it by RSS, email, or Twitter. You can also help build the feed by tagging new developments you encounter.
