CrossCheck – Verify Originality of Submitted Manuscripts
http://www.crossref.org/crosscheck.html

CrossCheck powered by iThenticate” is a new initiative from CrossRef to help the scholarly publishers verify the originality of submitted manuscripts. The need of a plagiarism tool was identified as a top priority by CrossRef members in 2006 and as a result CrossRef researched the best plagiarism tools on the market to provide a solution for the CrossRef members. CrossCheck is really two products, a database of scholarly publications and a web-based tool to check an authored work against that database. The web-based tool can be used in the editorial process to identify matching text but it can not, on its own, identify plagiarism. A human has to look at the matching text and use their best judgment to identify if plagiarism has occurred or not. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
