PaperChase is a service of the Beth Israel Deaconess Medical Center, a major teaching hospital of Harvard Medical School. On a not-for-profit basis, we provide access to the MEDLINE, AIDSLINE, and HealthSTAR databases of the National Library of Medicine, and the CancarLit database of the National Cancer Institute. PaperChase combines all four databases, over 9,500,000 references, into one file. This database of biomedical literature is the largest in the world. PaperChase is updated with approximately 10,000 new references weekly.
