Crossmark

Publishers can reassure readers that they’re keeping their content up-to-date and showcase additional metadata. Researchers and librarians can easily see the changes to the content they are reading, find out who funded the research, what licenses apply to the content and more. Anyone can access the Crossmark metadata through our REST API, providing a myriad of opportunities for integration with other systems and analysis of changes to the scholarly record. Publishers place the Crossmark button close to the title of an item of content on their web pages and in PDFs and commit to informing us if there is an update such as a correction or retraction. They also send additional metadata such as authors’ ORCIDs and the funders behind the research.
