The Department of Information Studies from the University of Sheffield has developed a very interesting way of presenting literature reviews, the Literature Roap Map. Here’s one on Learning Technologies in the Workplace.
It presents the literarure review in a tree structure, with links to the publications organised under headings. It is a very innovative way to organise existing publications on a given topic and share this with other researchers. There is no explanation as to how the map tool has been developed, is it a simple database with some Flash animations?
