Investigative journalist Colin Meek (who also leads courses in advanced online research skills) has created a visualisation on how to search the 'hidden' web.

Introducing the visualisation, Meek says when training others in research skills, he has found that there is "a lot of confusion about exactly why a lot of web content is 'hidden' from view and why ordinary search engines are not only hopeless at reaching 'hidden web' content they are doing an increasingly poor job of accessing breaking news or 'real-time media".

Follow this link to see Meek's "conceptual description of the four main data sources available to journalists and researchers: the hidden web, the searchable web, people and breaking news".

He includes notes on the best research tools available.
