How is Case different than PubMed?

Case includes scientific videos, audio transcriptions and research papers that PubMed doesn't have. Also, you can search and filter by Altmetric score, impact factor, number of citations and other criteria.

Is Case free?

Yes, our service is free. The only payment required is if you wish to view a full article and do not have a subscription to that medical journal. In this scenario, the payment goes to the journal, not to Case. If you have a subscription to the journal, you may log in with your username and password to access the full article. No payment required.

Why do I have to pay to view full articles?

We comply with the NIH's Copyright and Restrictions Policy, so Case works like PubMed. Abstracts and other public domain information are free, while full articles are property of the copyright owner and may require payment in order to view.
