Since 1946, the United Nations (UN) has produced an annual work known as the Yearbook. This volume serves as the principal reference work on the United Nations and their various activities. Recently, the UN digitized the Yearbooks from 1946 to 2005 and placed them on this very handy website. Visitors to the homepage can use the drop down menu offered here to look through any of the volumes that interest them. Within each volume, visitors can read through chapters, which usually include sections on political and security matters, economic and social questions, and a host of legal questions. For those persons looking for specific topics, each volume can be searched individually, or users may also wish to use the "Power Search" feature to refine their search even further. Finally, a "Share" feature allows users to share their findings via Google, Digg, Facebook, and other popular social networking sites.
