The proposal for the convergence of ECO National Libraries was granted to the ECO in 2007 by the National Library and Archives of the Islamic Republic of Iran. The ECO Cultural Institute, as the intercultural interface of the members of the ECO, played a significant role in convergence. In 2007, the National Library of Iran invited the heads of National Libraries and National Archives of the member states to co-sponsor the formation of a Library Assembly.
All countries except the Republic of Afghanistan and the Kyrgyz Republic took part in the primary meeting. At that meeting, due to the separate management of the Archive and Library section in some member countries, it was decided to focus exclusively on libraries.
The first meeting of ECO member Libraries was held in Tehran/Iran in November 2007. The meeting was scheduled to be drafted by Iran.
The second meeting was held in Baku / Azerbaijan in April 2009. All the participating countries, except Afghanistan, were present at the meeting. The draft statute was reviewed and approved after the amendments.
The third meeting was held in Ankara / Turkey in October 2010. Turkmenistan and the Republic of Uzbekistan did not attend the meeting.
From that date until November 2017, when the fourth ECO National Library Directorate Meeting was held in Dushanbe / Tajikistan, the meeting was postponed due to some issues.
