... [O]ur first manuscript (Programming Scala) is now available for public reading and feedback as part of our Open Feedback Publishing System. The idea is simple: improve in-progress books by engaging the community in a collaborative dialog with the authors out in the open. To do this, we ... built a system to regularly publish the whole manuscript online as HTML with a comment box under every paragraph, sidebar, figure, and table.
The open access movement:
Putting peer-reviewed scientific and scholarly literature

free of most copyright and licensing restrictions.
Removing the barriers to serious research.
