The partnership between the Rainbow Book Club and UNESCO contributed to the emergence of Port Harcourt as UNESCO World Book Capital 2014.

Although the Rainbow Book Club has collaborated with UNESCO for over nine years, it became an official UNESCO club on 28 November, 2017.

UNESCO clubs are an associative movement in support of UNESCO’s ideals. The Rainbow Book Club’s relationship with UNESCO dates back to 2008 when it held the ‘Get Nigeria Reading Again!’ campaign with Chief Emeka Anyaoku (Former Commonwealth Secretary-General) at the UN House, Abuja.

At the UN house, it held subsequent campaigns; 2009 with the then Minister of Information and Culture (Dr. Dora Akunyili) and 2010 with the then Minister of Petroleum Resources (Mrs Diezani Allison-Madueke).

This relationship has been sustained through the administration of UNESCO Directors/Country Representatives, Dr. Abimanyu Singh, Dr Joseph Ngu, Prof. Hassana Alidou.
