If the patron is logged into "My Account" in Stacks, they will be an authenticated EDS visitor and have access to the "Full Text" content without having to login again. If the patron is not logged into "My Account" in Stacks, they will browse EDS as a guest and be required to login when they find a resource they'd like to access the "Full Text" for. Other OPAC and catalogs will not authenticate on entry. A Stacks search bar can accommodate up to three (3) of these external catalog search configurations at one time. This capability is available without the ILS Integration option.
