is the oldest catalogue of the Web, started by Tim Berners-Lee,

they are expert

1, 2006): p7(1).

- Journal Gives Wikipedia High Marks for Accuracy, but Not for
Readability.(Nature )(Brief article). Dan Carnevale.
The Chronicle of
Higher Education 52.19 (Jan 13, 2006)
- “Other than errors, Nature's experts found that the Wikipedia entries
were often poorly worded and confusing. While the information was
generally reliable, the Nature article says, entries often lacked the
nuance that a subject-matter expert could provide, as well as good
editing.”
|
|

|
- Articles carry warning:
“As with any community-built reference, there is a possibility
for error in Wikipedia's content — please check your facts against
multiple sources and read our disclaimers for more information.”
