During the first half of 2007, the Department of Public Information continued to address key thematic priorities of the Organization, including issues relating to peace and security, climate change, the Millennium Development Goals and human rights. The Department has continued to expand its reach through the daily delivery of news and information products via radio, television and print and reaches an ever-widening global audience for text and audio-visual material via the World Wide Web. Using a combination of traditional means of communications and new information and communications technologies, the Department worked in close cooperation with Member States, United Nations system partners and civil society to expand its outreach and promotional activities. Increased emphasis was placed on reaching out to students and youth groups. The network of United Nations information centres played a key role in implementing the Department’s communications goals. The Dag Hammarskjöld Library continued its transition to a knowledge service for the Organization. Further steps were also taken to strengthen the culture of evaluation at all levels of the Department’s work. As a result, the Department’s public information capacity was strengthened.
