To say iParadigms' Turnitin (from $3 per student account) checks paper originality is like saying that a Swiss Army Knife has a blade. Yes, the Web-based Turnitin service scans papers against a prodigious database of journals, archived papers, and webpages (numbering in the thousands, millions, and billions respectively). And, yes, thanks to partnerships with both content aggregators and publishers such as CrossRef and EBSCO, searches are both wide and deep. But to describe Turnitin as a mere online plagiarism checker is to neglect the features that distinguish it from its competitors: course management, peer review, and online grading.
