Primary Databases: Should Use All Five
PubMed comprises more than 22 million citations for biomedical literature from MEDLINE, life science journals, and online books. Citations may include links to full-text content from PubMed Central and publisher web sites.
Contains high-quality, independent evidence to inform healthcare decision-making. Searches existing Cochrane (systematic) Reviews, as well as Cochrane (clinical) Trials.
Web of Science
The premier research platform to find and analyze scholarly research literature on Sciences, Social Sciences, Arts, and Humanities. Includes proceedings of international conferences, symposia, seminars, colloquia, workshops, and conventions.
Scopus uniquely combines a comprehensive, curated abstract and citation database with enriched data and linked scholarly content.
TRIP (Turning Research into Practice)
The free version of TRIP allows you to search for studies, including those indexed in EMBASE, and filter them by level of evidence. CMU Libraries does not subscribe to the paid version and so full text may not be available.
Secondary Databases: Use Depending on Topic
