The University of Virginia Library has launched its Libra institutional repository.
Here's an excerpt from the announcement:
Save your work in perpetuity with a new tool called Libra. A joint project between ITC and the University Library System, and requested by the Faculty Senate, Libra allows any employee of the University who produces scholarly works to store their papers, and in the near future, theses and datasets, in a secure location. Libra was developed specifically as a repository for peer-reviewed, scholarly articles, although other works such as books may also be deposited, as long as sufficient rights have been retained by the authors.
