I would like to choose the Wikipedia to be the only one encyclopaedia.Despite the the criticisms dogged by the vandals and questions about its accuracy,Wikipedia has became more and more popular in nowadays.
Wikipedia as a community-edited online encyclopedia,has thousands of volenteers who have created millions of entries in many languages.Whit this creative way,this site can provide the extremely fast and comprehensive coverage for it's readers.There is a popular arguement in the modern times - Your knowledge that you learned two years ago is invalid. so we need more fresh information and knowledge to compete with others. Becouse of the information from Wikipedia is immediately, people could get the most fashionable informations around the world,and also have a chance to see the different sides of one thing.
"Wikipedia is a freely licensed encyclopaedia.This means that anyone could copy it,redistrbute it.Commercially or noncommercially."Jimmy Walse the founder and chairman of the Wikipedia Foundation said that in a interview with Dale Hioberg the senior president and editor chief of Encyclopedia Britannica Inc.With this wonderful way people can communicate wiyh each other for free charge.I think it enhances the circulation of knowledge.
Jimmy Walse also said that "openness"is going to be neceseery in order to reach the highest levels of quality.Britannica has long been a standard bearer,and they have done a fine jod within their model.But it si time to work in a different model,with different techniques made possible by new technologies but the same goals,to reach ever higher standards.What's more, a recent study in the journal Nature, however, found few differencies in accuracy between science entries inWikipedia and the venerable Encyclopaedia Britannica.
In my opinion,althougth the Prorietary encyclopaedias have lots of scholars and experts around the world who serve as the contributors and advisers for them,it seens that their informations are more reliable than Wikipedia.On the other hand,Wikipedia is use a different models to gather information and knowledge.These two encyclopaedia models are sharing the same goals.With high technology and new concept,Wikipedia are puting more emphasis on quality instead of quantity.
