The University of Guelph's School of Environmental Sciences has adopted an open access policy.
Here's an excerpt from the policy:
Researchers in the School of Environmental Sciences commit to making the best possible effort to publish in venues providing unrestricted public access to their works. They will endeavour to secure the right to self-archive their published materials, and will deposit these works in the Atrium.
The School of Environmental Sciences grants the University of Guelph Library the non-exclusive right to make their scholarly publications accessible through self-archiving in the Atrium institutional repository subject to copyright restrictions. . . .
This policy applies to all appropriate scholarly and professional work produced as a member of the School of Environmental Sciences produced as of the date of the adoption of this policy. Retrospective deposit is encouraged. Co-authored works should be included with the permission of the other author(s). . . .
Works should be deposited in the Atrium as soon as is possible, recognizing that some publishers may impose an embargo period.
This policy is effective as of 11/05/2009 and will be assessed a year after implementation.
