Wikipedia V.S Encyclopaedia Brittanica

I think Encyclopaedia Brittanica is better than Wikipedia because it provides more accurate information to people. As encyclopaedia brittanica is only allow particular experts to upload or change the information and it has a high monitoring process on the website, so there is a promise of it's accuracy and quality. Someone may argue that, wikipedia lets some unknown "experts" upload the information, let the encyclopaedia has a wider range of information. However, those information has not much confirm and the information may be wrong. How are the effects of provideing uncorrect information? Although encyclopaedia brittanica may use more time or cost to find and check the information, it is worth because accuracy is the most important thing of an encyclopaedia. If an encyclopaedia provide wrong information, it needs higher cost and more time to solve the problem.
