A way back, Michael Geist, commented on whether copyright owners could control access to freely available online content. AccessCopyright, seeks to limit deep linking to its Captain Copyright marketing, to sites that are supportive of its mission, henceforth silencing critical commentary.

Michael commented that courts in Canada and the United States have concluded that links do not raise copyright concerns. I'm guessing this "oversight" will be addressed in the next revision of the Copyright Act.

Why do I care? Scholars need deep linking to cite works they are using or addressing, if we can't deep link, we can't build on what exists.
