EndNote Click (formerly Kopernio) is a free web browser extension that helps researchers find and download PDFs from legally authorized sources such as publishers, open access repositories, and other document archives. EndNote Click works with Vanderbilt's subscriptions to bring you paywalled articles that you are entitled to access using your VU credentials. If no subscription access is available, EndNote Click will try to deliver a free alternative, e.g. an OA version or preprint. More information on setting up an account can be found here.
