Here’s a fun fact: Cleveland Public Library has been a United Nations Depository library since 1947 and it is recognized as the official UN deposit library for the state of Ohio. The UN Deposit Library System is an important part of the United Nation’s outreach and education effort and consists of over 400 libraries in 140 different countries. This means that the Library receives official UN Documents that are archived in the Social Sciences Department  on the 5th Floor of the Louis Stokes Wing.
