"In 2005, at the height of the controversy over the site's accuracy, Mr Wales told the BBC that students who copied information from Wikipedia "deserved to get an F grade".

Mr Wales said the website still lacked the authority to be used as a citeable source for college-aged and university students.

But he said new editing and checking procedures had made Wikipedia more trustworthy.

Changing procedures

Since the controversy, in which it emerged that the "free editing" policy had allowed articles containing inaccuracies and bias to appear, the site has introduced a system of real-time peer review, in which volunteers check new and updated articles for accuracy and impartiality."
