Google News has launched an experimental new feature, an option to filter news queries by source.
The source-filtering device allows users to decide between viewing all related articles, filtering results to just show news blog results or to view just the local sources from within a cluster of articles.
The news cluster around the transfer of former Bosnian Serb leader Radovan Karadzic to The Hague is a good example of how the feature works.
The image below shows how in total Google News returns 3,651 English-language sources for this story, breaking the number down for blog reaction from 36 established news outlets and offering a more local focus with 20 sources from Serbia and 16 from the Netherlands.
The introduction of the source-filtering feature follows tests, earlier this month, of a series of new experimental features.
According to the Google watching blog, Google Operating System, the search giant has been experimenting with a Google News redesign incorporating an images area, a featured photo, an area dedicated to monitoring developing stories and highlighting pull quotes from specific stories across its different sections.
