CrossMark is a system that identifies publisher-maintained versions of scholarly works and tracks updates to those works over time. The summary discusses: 1) What CrossMark is and how it tracks updates and versioning of scholarly works. 2) Growth in CrossMark deposits and participating publishers since 2013. 3) Proposed changes to the CrossMark schema and requirements for publishers to upgrade to the new schema in early 2015. 4) An upcoming new feature of CrossMark to link scholarly works to clinical trials information.
