What is CrossCheck?
"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 to 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.
This database is one of two parts that make up the CrossCheck service. The second part is the iThenticate tool, which compares authored work against the content in the database and highlight matching or similar text for further editorial review."
