Web scale discovery services have stronger functionality than Google Scholar for searching library resources. Discovery services allow limiting searches to a library's subscribed resources only, to peer-reviewed articles only, and integrate a library's catalogue and institutional repositories. They support more filtering facets and integration of subject indexes, Scopus, and Web of Science. However, Google Scholar may update search results more quickly, cover more open access and free sources, and have better relevancy and consistent features due to its focus on article searching.
