Consumers International has released Access to Knowledge: A Guide for Everyone.
Here's an excerpt:
Access to knowledge (A2K) is the umbrella term for a movement that aims to create more equitable public access to the products of human culture and learning.
Fields of advocacy that it subsumes include most centrally copyright and patent law reform, open access, open data and open standards, but also access to public information, broader communications rights such as freedom of expression, and issues around ownership of and participation in public media.
