I had heard of the One Laptop Per Child program months ago but it wasn't until I heard fellow librarian Rochelle Mazar speak about how she used the project to engage students with the "issues of information access and activism" that I made the connection between the work of the OLPC and the professional work that many librarians are engaged in.
The connection that came to mind was not between libraries and formal development efforts (although there are organizations like eIFL.net and Librarians Without Borders that do this) but the work that libraries are currently contributing to on the "open" front: open source, open standards, and open access.
Thankfully, there is the Internet Archive's Open Content Alliance that have partnered with (fellow) libraries like The University of Toronto to ensure that the world's treasures are available to all of the world.
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.
