Top online encyclopedias alternative to Wikipedia

These are some decent alternatives to Wikipedia, the online wiki that anyone can edit and contribute to, other online encyclopedias have taken a more restrictive approach as to who can create an article, some of them will ask the author to use his/her real name as well as proving accreditation of any qualification the author claims to have, others do not allow users to contribute articles and are written by experts hired by the company, the final goal is always the same, to create a reliable accurate encyclopaedia containing a wide range of subjects for students, researchers and those in search of knowledge.
