The World Digital Library (WDL) is a website, www.wdl.org, which provides free access to primary cultural heritage materials that tell the stories and cultural achievements of all countries. The WDL is a joint effort of the Library of Congress, United Nations Educational, Scientific and Cultural Organization (UNESCO), and over 120 participating institutions around the world. This poster session will introduce the WDL by presenting brief history of the WDL, its objectives, contributors, content, capacity building, and features. The poster will also show how the WDL web site is used by the people around the world.
