Almost 30,000 downloads of KU Pilot Collection titles from 165 countries



In March 2014 Knowledge Unlatched started to unlatch books in its Pilot Collection, making them available to anyone in the world to read or download for free on a Creative Commons licence. This was the culmination of a behind-the-scenes process of loading the titles onto our partner host platforms: OAPEN and HathiTrust. The books became live on the OAPEN platform first – followed soon after by HathiTrust. The final book in the Pilot Collection was published and made OA on 2 September 2014.

You can view a list of Pilot Collection titles and download them via the KU collections website here.

Internet Archive Statistics

All but one of the books in the KU Pilot Collection are available on Creative Commons Non-Commercial licences that allow for sharing with others, as long as it is for non-commercial purposes. This means that users have permission to share PDFs with each other directly via email or messenger. It also means that the books can be made available for download for platforms other than OAPEN and HathiTrust, which KU is partnering with directly. One book is on a CC BY ND licence which allows others to use commercially.

This approach to licencing is already helping to increase the reach of the KU Pilot Collection titles. has posted the majority of the books in the Pilot Collection to the Internet Archive, increasing their visibility and discoverability and helping to promote the KU project and the publishers that are engaging with it. KU uploaded the remaining few books to the Internet Archive recently.
