EUCLID is Emory's online library catalog for finding books and journals, though it does not contain article titles. Databases@Emory contains almost 600 databases, some with full-text articles and others with citations to find related articles. DiscoverE allows searching across EUCLID and most databases@Emory. WorldCat is the union catalog of US research libraries, and can be used to request items not available in EUCLID through interlibrary loan. Google Scholar includes academic articles both within and outside Emory, some with full text and some as citations only.
