New research collaboration tools are being released all the time. For example, you can find a list of existing tools here.

Now ColWiz has been released. It promises to combine the functionality of a range of individual tools into one. It allows you to collaborate, manage different projects, organise events, mark up research content, manage references and more. You can also use it to visualise your own research trends via graphs, patterns and charts. The service is only available to those with a bona fide university email address, and you will need to download and install software to be able to use it. It is available in Windows, Macintosh and Linux versions.
