See the piece by Robert Darnton, Director of the Harvard University Library:
"The motion before the FAS in support of open access to scholarly articles concerns openness in general. It is meant to promote the free communication of knowledge. By retaining rights for the widest possible dissemination of the faculty’s work, it would make scholarship by members of the FAS freely accessible everywhere in the world, and it would reinforce a new effort by Harvard to share its intellectual wealth."
