PRESS RELEASE

CrossRef Announces CrossCheck Plagiarism Detection Service

LYNNFIELD MA, April 15, 2008. - CrossRef announces an agreement
with iParadigms, LLC to launch the CrossCheck service to aid in
verifying the originality of scholarly content. Following on the
success of CrossRef's recent pilot of CrossCheck, the service is
scheduled to go live in June.

CrossRef is partnering with iParadigms, LLC to offer its members
- leading scholarly and professional publishers - the opportunity
to verify the originality of works submitted for publication
using the iThenticate service to check against a vast database of
proprietary as well as open web content. Until now, there was no
automated way to check submissions against previous publications
because the published literature had not been indexed and 'text
fingerprinted' for this purpose. The CrossCheck database will
include the full-text journals of leading academic publishers,
and is expected to grow very rapidly over the coming months as
CrossRef member publishers sign up for the service.

CrossCheck will be available to all CrossRef members who opt to
contribute their content to the database. To use the service
publishers will need to integrate the checking tool into their
editorial processes and develop suitable policies and guidelines.
CrossRef is working with iParadigms, member publishers, and
editorial system software producers on appropriate technical
information and guidelines for CrossCheck.

Ed Pentz, CrossRef's Executive Director said, "CrossCheck builds
on the collaborative nature of CrossRef itself, and will provide
an important tool for ensuring the originality of scholarly
content.  The system doesn't actually detect plagiarism -
plagiarism implies intent and that's not something computers can
identify.  Instead it identifies matching text in different
documents and then a knowledgeable person has to look at the
results as part of the editorial screening process.  We are
pleased to be working with iParadigms and using the iThenticate
service.  Ultimately, the whole research community will benefit
from CrossCheck."

John Barrie, President and Founder of iParadigms, LLC added,
"iParadigms is the world's leading provider of web-based software
solutions that analyze the originality of textual materials. Our
services, including Turnitin and iThenticate, are used by over
8400 institutions in 106 countries, to help professionals such as

to the rigorous standards of integrity and timeliness in our
fast-paced, web-connected world. The inclusion of CrossRef member
scholarly and scientific content in our database makes our
services even more effective than ever. This is a win for both of
our organizations."
