Online encyclopedia

An online encyclopedia or a wiki is a type of encyclopedia with digital content and may include collaborative editing. Some examples of this, are Encyclopedia Britannica or Allpedia.

History
The idea to build a free encyclopedia using the Internet can be traced at least to the 1993 Interpedia proposal; it was planned as an encyclopedia on the Internet to which everyone could contribute materials. The project never left the planning stage and was overtaken by a key branch of old printed encyclopedias.

Wiki's
Wiki's such as Wikipedia are created by wiki software such as MediaWiki or DokuWiki. The first wiki that did not include collaborative editing was called Nupedia. The idea of Nupedia was for articles to be verified by verified editors and allowed to be seen on the website. That was then replaced with Wikipedia and Conservapedia being it's alternative.
