Crossref Similarity Check and iThenticate Publishing Screening Services

Digital Academic Research & Publishing

Crossref Similarity Check (iThenticate Engine)

The exact similarity screening database used by journal editors worldwide—cross-referencing 82+ million paywalled articles from leading academic publishers.

See What Journal Editors See Before They Open Your Manuscript

Standard free web plagiarism tools only crawl public internet pages; they cannot access paywalled academic journals locked behind publisher subscriptions. When you submit your manuscript to an Elsevier, IEEE, or Springer journal, the editorial office runs it through the Crossref Similarity Check (powered by iThenticate).

At IJRDO, we provide authors and university researchers with official Crossref Similarity Check reports. By reviewing the exact same similarity dossier that editors evaluate, you can detect accidental phrase matches in paywalled literature and rectify them before submission.
