Therapy - Open Access in Clinical Medicine is a newly launched OA title from Future Drugs. This title is Future Drugs first foray into the OA realm. Their other nine Expert Reviews... journals are of the traditional toll access (subscription) variety.
Quoting a blurb on the journal's main page:
The journal follows a 'hybrid' model, whereby open-access publication of original research papers will be supported by high added value content - reviews, commentaries, profiles and news, which can paid for by subscription or pay-per-view. Articles published in the original research section will be available to download for personal use directly from the site without charge.
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.
