CrossRef and iParadigms will launch CrossCheck in June, which will allow publishers to analyze content in both publisher systems and Internet Web sites in order to identify works that may have been plagiarized.
Here's an excerpt from the press release:
CrossRef is partnering with iParadigms, LLC to offer its members—leading scholarly and professional publishers—the opportunity to verify the originality of works submitted for publication using the iThenticate service to check against a vast database of proprietary as well as open web content. Until now, there was no automated way to check submissions against previous publications because the published literature had not been indexed and "text fingerprinted" for this purpose. The CrossCheck database will include the full-text journals of leading academic publishers, and is expected to grow very rapidly over the coming months as CrossRef member publishers sign up for the service.
CrossCheck will be available to all CrossRef members who opt to contribute their content to the database. To use the service publishers will need to integrate the checking tool into their editorial processes and develop suitable policies and guidelines. CrossRef is working with iParadigms, member publishers, and editorial system software producers on appropriate technical information and guidelines for CrossCheck.
