Encarta encyclopedia tests edit system, from AP

Microsoft Corp.’s Encarta encyclopedia is testing a system that lets everyone be an editor – in theory at least.

Readers can suggest edits or additions to entries, although the changes are vetted by editors before they reach the page.

Encarta is not requiring such novice editors to identify themselves, said Gary Alt, Encarta’s editorial director. But it is asking them to reveal the source of their information if possible, and the editorial staff will check for both factual errors and evidence of bias.
