Where the published evidence lives. Bibliographic indexes, open archives, systematic-review libraries and point-of-care references — the substrate every disease-research question eventually returns to.
The world's most widely used biomedical bibliographic database, with over 38 million references to journal articles across medicine, nursing, dentistry, veterinary medicine and the life sciences. MEDLINE forms its curated core, drawing from 5,200+ peer-reviewed journals. The standard starting point for any disease-related literature search.
PMC is the open-access full-text archive of biomedical and life-science literature maintained by NIH; Europe PMC is its European counterpart at EMBL-EBI. Together they hold millions of free full-text articles, preprints and grant-linked outputs — essential when PubMed's abstract-only records aren't enough.
Elsevier's biomedical and pharmacological database with more than 45 million records from over 8,500 journals plus conference abstracts and preprints. Overlaps with MEDLINE but adds substantial European and pharmacology-heavy content, making it standard for systematic reviews and drug-safety work.
Aggregates Cochrane systematic reviews and the CENTRAL register of controlled trials, produced by international review groups that maintain rigorous evidence-synthesis standards. The leading source for evidence-based summaries of interventions across virtually every disease area.
Clinician-facing decision-support resources that synthesise current evidence into continuously updated, topic-organised articles on diseases, treatments and diagnostics. Heavily used at the point of care and behind paywalls at most teaching hospitals worldwide.
Elsevier's integrated clinical reference platform combining textbooks, journals, practice guidelines, drug monographs and procedural videos in one search. Widely used as a clinical reference for diseases across all medical specialties.
Provides consumer-friendly information on more than 500 diseases and conditions, with content drawn from NIH and other vetted sources, plus encyclopedia entries, drug information and Spanish-language material. The go-to NIH-quality patient-facing resource.
