Tools against plagiarism

Respecting copyright and properly referencing sources are demanded of students. Ouriginal (formerly Urkund) is a plagiarism detection tool available to LiU teachers for checking texts written by their students. To promote students’ abilities in citing and referencing, Linköping University Library has created NoPlagiat, a self-study tutorial on plagiarism and copyright. Both Ouriginal and NoPlagiat can be accessed through the Lisam learning platform.


Ouriginal (formerly Urkund) is a text-recognition system that looks for similarities between a submitted document and external sources. The system is available in Lisam and it is possible to connect Ouriginal to the submission module in a Lisam virtual course room. As a teacher at LiU, you have the option to have an account for Ouriginal, which can be provided by the library.  

When a text written by a student is sent to Ouriginal, the document is checked against three main sources: the Internet, published material (excluding some publications because of commercial copyright reasons) and works by students. If the document shows similarities with content from these sources, the system will indicate these similarities. The analysis is presented in a report that is sent to the teacher that requested the analysis, who then makes the judgement if there are grounds to suspect plagiarism.

NoPlagiat self-study tutorialShow/Hide content

To promote students’ knowledge of copyright and abilities in citing and referencing, Linköping University Library has created NoPlagiat, a self-study tutorial that LiU teachers can incorporate as part of a course in LiU’s learning platform Lisam.

The purpose of NoPlagiat is to increase students’ awareness about plagiarism and teach them how to avoid it. The self-study tutorial consists of five sections:

  • What is plagiarism?
  • Referencing
  • Citing
  • Paraphrasing
  • Copyright

After each section, the student’s knowledge is tested with some questions. It will take approximately 30 minutes to complete the whole tutorial.

NoPlagiat is especially suited to prepare students for paper writing and other similar assignments and is available in both Swedish and English. 

When students have completed the tutorial, their answers are saved in the evaluation overview, making it possible to include as a mandatory part of the course. The Library can help you install NoPlagiat in the proper course room in Lisam.

If you have any questions, want a demonstration, or want us to install NoPlagiat in your virtual course room in Lisam, please contact us at
