Serials Solutions, a business unit of ProQuest, has signed new beta development partners and new content providers to its new Summon unified discovery service. University of Sydney and University of Liverpool join Dartmouth College and Oklahoma State University as a beta development sites for the new service. New content will be contributed from the American Psychological Association (APA) and Alexander Street Press. The service is being developed in cooperation with library beta partners, with a goal of bringing the researcher back to the library and providing a greater return on the library’s content investment. The Summon unified discovery service creates a library-branded search box that provides users a starting point for library research. The hosted service is built with an open API that will allow it to integrate with existing library websites or campus systems with low impact on staff.
