Kopernio: Home

Kopernio is a browser plugin developed by Clarivate, the parent company of Web of Science. It works behind the scenes in your browser to get you the best PDF copy of articles that you're looking for. Kopernio can be used both on or off campus and uses existing authentication infrastructure to leverage library subscriptions. The plug in stores your IMSS credentials on your local machine and employs them when you're doing a literature search. Kopernio has a detailed page that describes their data principles. Caltech users have been upgraded to premium accounts that come with 2GB of locker storage.                  To get started - follow the directions on this Kopernio-Caltech guide
