As announced at CLEF 2013, the CLEF Association is a new-born not for profit legal entity committed to make CLEF happen. The CLEF Association will support the costs for its central coordination, as well as the preparation of Lab working notes and Springer proceedings. As a member you will be able to make use of the resources provided by CLEF and be part of a community interested in topics surrounding the evaluation of multilingual information access systems.

In the registration process, you will be presented with a link to the CLEF Association statue. If you do not want your details to be kept on file by the CLEF Association, please untick the check box for the question "I have read and agree with the CLEF association statute, and would like my registration details forwarded to the CLEF association."
