The aim of this site is to bring together in one place links to selected documentary films that are streamed on other sites across the web e.g. GoogleVideo, YouTube, Guba, MegaVideo, Youku etc., and organise them by subject matter such as 9/11, art & artists, drugs, economics, environment, health, comedy, history, religion, music & performing arts, science, philosophy, politics, society, technology, biography, etc. A clear warning is issued that TDF has no control over copyright issues relating to the streaming media. The site quotes reputable reviews of the documentaries and provides a space for comments from viewers.There is also an online store, linked to Amazon, where thousands of the films are classified into categories for ease of purchase.
