OhioLink Central catalog
Heterick Memorial Library participates in OhioLink, a computer network of Ohio academic libraries. OhioLink maintains a 10 million + item central catalog of the member libraries. ONU faculty and students can search the OHIOLINK central catalog in addition to Northern's own POLAR online catalog.
Patrons can themselves request items in the central catalog not available at ONU. Items are delivered to Heterick via a commercial courier service. Ask at the Reference or Circulation Desk for details.
OhioLink also offers numerous research databases which can be reached locally through the Heterick home page.
