From FastCompany:

Most medical journals are locked behind paywalls online; the Internet’s largest free database of medical journal articles, PubMed Central, has large content gaps. A somewhat similar project at Cornell University to offer free access to physics, mathematics, and computer science papers, arXiv, has become an academic staple in recent years. Earlier in 2012, Harvard University openly criticized the high cost of medical journals.
