The Network seeks to promote the exchange of nuclear information and to strengthen strategic partnerships amongst members.

In 2008, at the meeting of INLN Members and prospective members, during the 34th International Nuclear Information System (INIS) Liaison Officers Meeting in Vienna, a large number of nuclear libraries from around the world expressed their interest and subsequently joined the INLN: the Belarus INIS Center, Chair of Ecological Information Systems, the Nuclear Research Institute Rez plc of Czech Republic, the Egyptian Atomic Energy Authority (EAEA), the Ghana Atomic Energy Commission Library, the Bhabha Atomic Research Centre (BARC) of India, the Radiological Protection Institute of Ireland, the Japan Atomic Energy Agency (JAEA), the Instituto Nacional de Investigaciones Nucleares (ININ), Centro de Información y Documentación Nuclear (CIDN) of Mexico, the Centre National de l' Energie des Sciences et des Techniques Nucléaires (CNESTEN) of Morocco, the Korea Atomic Energy Research Institute (KAERI) at the Korea University of Science and Technology, the Vinca Nuclear Institute of Serbia, the Centre National des Sciences et Technologies Nucléaires (CNSTN) of Tunisia.

In January 2009, the Commissariat à l'Énergie Atomique (CEA) - Centre de Saclay - Centre de Ressources Documentaires joined the Network, while in 2010, the National Atomic Energy Commission, the Norwegian Radiation Protection Authority, and the Pakistan Institute of Nuclear Science & Technology decided to become INLN members.

The Nuclear Energy Regulatory Agency of Indonesia - Badan Pengawas Tenaga Nuklir and the New Zealand Institute of Environmental Science and Research – National Radiation Laboratory are the newest members, raising the total number of Nuclear Libraries/Information Centres participating in the INLN to 37.

The success of INLN is based on its democratic structure: all participating libraries are equal partners, valued according to what they bring as practitioners in terms of information and their willingness to share, rather than on predetermined hierarchical or status levels.
