According to a study commissioned by the international Committee on Publication Ethics (COPE), over 40% of journal editors worldwide screen manuscript submissions against the iThenticate database. They do this via the CrossCheck service —the publisher-facing version of iThenticate available from the DOI agency CrossRef.

An example of a publisher's policies using CrossCheck/iThenticate is available in the Springer Nature CrossCheck Guide online at

In another example, Elsevier has integrated CrossCheck and iThenticate into their editorial submission system to ensure that all manuscripts are checked. Yet Elsevier editors understand the importance of combining the generated similarity reports with sound judgment. As explained by one of their editors-in-chief, commenting in "How CrossCheck can combat the perils of plagiarism":

It depends very much on whose text is reused and in which part of the paper. There’s a big difference between similarities in the research methodology descriptions and the actual research findings.

Not sure if your publisher is basing editorial decisions on iThenticate similarity reports?

You may wish to check the Author Guidelines for the publisher or journal of interest to see if they mention iThenticate or CrossCheck or CrossRef Similarity Check.

The publisher website may include an iThenticate badge such as this:

iThenticate Button 1

For example, the Copernicus website at clearly indicates use of iThenticate.
