From A. A. Adams, Copyright and research: an archivangelist’s perspective, SCRIPT-ed, September 2007:
To be an academic carries with it a great deal of freedom, or at least it should. At a time when pressures on academic freedom are rife, everywhere from Australia to Zimbabwe, academics should be confronting the responsibilities that go with their cherished and fought-for freedoms. That responsibility is to disseminate one’s work as widely as possible, to hold it up for criticism and to allow others to build on it. To do so demands that we hold Open Access to our articles as a categorical imperative and not allow the tail of academic publishing to wag the dog of academic communication.
