Book publishers have long used free content as part of their marketing and selling efforts, with the vast majority of free content distributed in printed form. Digital distribution of free material, either intentional or via unauthorized availability through peer-to-peer sites and other Web outlets, offers a fast and expansive connection to consumers, but content can also be copied and disseminated without publishers' control. Some publishers are torn between the efficiencies digital distribution provides and concerns over piracy and print-sale cannibalization. This research report is part of an ongoing effort by O'Reilly Media Inc. and Random House to test assumptions about free distribution, P2P availability and their potential impact on book sales.
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.
