The social media account @UNYearbook has been regularly tweeting under the hashtag #UNYearbookinAction about how researchers and scholars have recently used the Yearbook of the United Nations as a source for their articles and books. The series also highlights how authoritative institutions such as the libraries of Oxford and Yale promote the Yearbook as an authoritative reference for expanding knowledge of United Nations activities and concerns. The series, which regularly appears on Thursdays, has highlighted academic work on topics ranging from the history of the Organization and the drafting of the Universal Declaration on Human Rights to United Nations gender politics in Africa and the funding rules of international organizations, along with relevant political, economic and social affairs from the inception of the United Nations through the Cold War to the present era. Reader response in numbers of impressions has revealed a keen interest in #UNYearbookinAction among @UNYearbook followers.
