  As scholars migrate into online spaces like Mendeley, blogs, Twitter, and
more, they leave new traces of once-invisible interactions like reading,
saving, discussing, and recommending. Observing these traces can inform new
metrics of scholarly influence and impact -- so-called "altmetrics."
Stakeholders in academia are beginning to discuss how and where altmetrics can
be useful towards evaluating a researcher's academic contribution. As this
interest grows, libraries are in a unique position to help support an informed
dialog on campus. We suggest that librarians can provide this support in three
main ways: informing emerging conversations with the latest research,
supporting experimentation with emerging altmetrics tools, and engaging in
early altmetrics education and outreach. We include examples and lists of
resources to help librarians fill these roles.
