URKUND matches submitted text against material from three different source areas:

The Internet (approx. 10 billion web pages)
Published material (see below)
Previously submitted student texts (over 1.5 million. Feb.2009)

URKUND has formed strategic partnerships with a number of leading information providers, such as DIVA (Digital Scientific Archive), Iustus, Nationalencyklopedin and ProQuest. This mean that much published material is a part of the plagiarism checks. The source area contains scientific and popular articles, references books and databases and more. URKUND continuously work towards creating more partnerships to benefit our clients in their work with plagiarism.

It is also possible for clients to add their own sources, such as internal databases to the plagiarism checks. Please contact URKUND for more information.
