See esp. the chapter on Results of Digitisation Projects and Access. Table 8 in that chapter ("Means of User Access to the Digitised Content") shows that in 10 of the 12 surveyed countries, users don't have to pay for access to the resulting digital editions.

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.
