When it comes to Info Source, I'm not too familiar with it, but I'm reading the special report from the OIC, and there's some concern that information that would provide Canadians with a working knowledge of how to make requests in a more efficient way has been taken down, and the response seems to be that it's available on the Internet on government websites otherwise. Why would we not simply provide a digital version of Info Source? Perhaps that is the intention.
