The usability tests were recorded on video and can be seen over at DEFF’s wiki. I haven’t seen them all yet, but the ones I did see were quite instructive! Enjoy.
Please note that the clips CANNOT be downloaded for personal use. If you need to know more, contact Birgitte Munk at the Royal Library: firstname.lastname@example.org
PS. Apparently DEFF are publishing the news about the videos on Monday on their website. I was just faster…;-)
