For my active blogs, please see:
Sustaining the Knowledge Commons (2014-) is a team research blog dedicated to a SSHRC-funded Insight Development Grant project focused on the economics of transition to open access (e.g. open access article processing charges, resource requirements for small scholar-led journals).
The Imaginary Journal of Poetic Economics (2004-) is a long-standing individual scholarly blog. Examples of series include The Dramatic Growth of Open Access and Creative Commons and Open Access Critique Series. My current focus (as of May 2015) is current issues in copyright and licensing for open access.
