A librarian can help health sciences students effectively search databases and the literature for relevant information. The top databases for health information at Yale include MEDLINE, Scopus, CINAHL, and Web of Knowledge. These databases index journal articles and literature that can be accessed via Yale Links. The National Library of Medicine also provides specialized databases on topics like toxicology, environmental health, and emergency management. A librarian can help formulate search strategies, identify relevant keywords and subjects, and recommend additional resources. They can also assist with managing references and citations using bibliographic software like RefWorks.
