A compilation of resources about the COVID19/Coronavirus pandemic


Curated Zotero Citations from Yale Medical Library

The Cushing/Whitney Medical Library has developed a public collection of COVID-19 citations to aid the research and clinical practice missions of the Yale Schools of Medicine, Public Health, and Nursing and the Yale New Haven Hospital.

The collection, accessible through this public Zotero library (no account required), includes daily updates from PubMed,, Disaster Lit, and preprints* from bioRxiv and medRxiv. The citations have roughly been sorted into different topics: epidemiology, immunology, modeling, sequencing, and treatment. There are also folders for different regions and the ability to view the collection by citation source.

Most records include abstracts and all include links for users to pursue full-text access. To access the URL, click on a citation and scroll down to the URL field.
