NATO Library
"NATO Library is a specialised research library that serves NATO Staff, delegations, missions and external researchers. Our mission is to support NATO’s goals and objectives by making credible and timely public information resources and services available to NATO Headquarters.
NATO Library shares its space with The Archives Reading Room, so primary and secondary research materials about NATO, its activities, and its history can now be conveniently consulted in a single shared physical location in the home of the Alliance."
