As part of its mandate to preserve and provide access to historical United Nations documents, the Dag Hammarskjöld Library has completed the digitization of an important series of Security Council documents: the supplements and special supplements to the official records.

The supplements were issued quarterly from 1946 to 1998 and consist of selected documents and a comprehensive checklist of the Council’s documents.

Special supplements were issued between 1946 and 1992. They contain important reports from other UN organs and subsidiary bodies requested by the Security Council.

These official documents, comprising over 1,152 files and more than 128,000 pages, are now accessible through the UN Digital Library to serve as essential references for researchers and historians worldwide.

Preserving the Past to Power the Future

The digitization of these important documents represents a significant achievement – but it’s just the beginning. With over 12.64 million pages of 790,000 essential UN parliamentary and normative documents still waiting to be digitized, the Dag Hammarskjöld Library is seeking external support to accelerate this monumental effort.

With the right backing, we can vastly expand access to the UN’s historical record, empowering Permanent Missions, researchers, educators, and citizens around the world to engage more deeply with the Organization’s legacy and decision-making.

We welcome your ideas and suggestions for foundations or charitable institutions around the world that may be interested in supporting this vital knowledge preservation project. Please reach out to us at library-ny@un.org.
