CrossRef is an independent membership association founded and directed by publishers. CrossRef’s mandate is to connect users to primary research content, by enabling publishers to work collectively. CrossRef is also the official DOI® link registration agency for scholarly and professional publications. Our citation-linking network today covers tens of millions of articles and other content items from thousands

of scholarly and professional publishers.

CrossCheck powered by iThenticate is an initiative started by CrossRef to help its members actively engage in efforts to prevent scholarly and professional plagiarism. Although there are several plagiarism screening  tools already available, they are not well-suited for filtering academic content simply because they haven't had access to the relevant full-text literature to screen against. CrossCheck changes this by creating and continuously growing a database of current and archival scholarly literature.
