Beginning in Spring 2013, the Penn Libraries has licensed iThenticate, plagiarism-checking software for instructors, researchers, graduate students, and undergraduates engaged in high-level research at the University of Pennsylvania. This tool checks for plagiarism against scholarly databasesas well as the Internet.

Users of  iThenticate should be aware that the product is subject to an End User License Agreement (EULA). This agreement takes the form of a “pop-up” window. You must click “I agree” in order to proceed and use the product. We want you to be informed about the agreement and what it entails and therefore very strongly encourage you to read the entire EULA, as it details your rights and responsibilities as a user of iThenticate. Please note that the EULA is an agreement directly between the user and iParadigms, the company which licenses iThenticate, and does not involve the Libraries or the University. The Libraries have a separate licensing agreement that allows us to install and use the product.
