The International Coalition of Library Consortia (ICOLC) first met informally as the Consortium of Consortia (COC) in 1997. The Coalition continues to be an informal, self-organized group comprising (as of September 2000) nearly 150 library consortia from around the world.

The Coalition serves primarily higher education institutions by facilitating discussion among consortia on issues of common interest. At times during the year, ICOLC may conduct meetings dedicated to keeping participating consortia informed about new electronic information resources, pricing practices of electronic providers and vendors, and other issues of importance to directors and governing boards of consortia. During these sessions, the Coalition meets with members of the information provider community, providing a forum for them to discuss their offerings and to engage in dialog with consortial leaders about issues of mutual concern.

DEFF participates every year in the International Coalition Of Library Consortia (ICOLC) and have been involved in the planning of this event.
