 In 2007, Michael Gorman, former president of the American Library Association (ALA) stated in an "Encyclopædia Britannica" blog that "A professor who encourages the use of Wikipedia is the intellectual equivalent of a dietician who recommends a steady diet of Big Macs with everything".The library at Trent University in Ontario states of Wikipedia that many articles are "long and comprehensive", but that there is "a lot of room for misinformation and bias [and] a lot of variability in both the quality and depth of articles".It adds that Wikipedia has advantages and limitations, that it has "excellent coverage of technical topics" and articles are "often added quickly and, as a result, coverage of current events is quite good", comparing this to traditional sources which are unable to achieve this task.
