The UNESCO Digital Library is a key tool for enabling UNESCO’s mission of building peace in the minds of people, in particular by “advancing the mutual knowledge and understanding, and encouraging cooperation among the nations in all branches of intellectual activity, including […] the exchange of publications, objects of artistic and scientific interest and other materials of information” (UNESCO Constitution).
In more concrete terms, it provides access to publications, documents and other materials either produced by UNESCO or pertaining to UNESCO’s fields of competence. These collections are accessible online or physically - at the library or the archives room.
The UNESCO Digital Library is constantly enriched with new publications and documents produced by UNESCO, as well as with acquisitions, resources shared by other institutions and donations. Furthermore, new digital materials are produced daily under a major ongoing project “Digitizing our shared UNESCO history”, which allows to preserve and share thousands of collection items, previously unavailable electronically. They will be integrated in the UNESCO Digital Library in the near future.
