OpenHistory is a free open source encyclopedia mainly covering Japanese history and notable people during Japanese history. Much of the content is used as a basis for articles in the Wikipedia Encyclopedia. It is available for free use under the GNU Free Documentation License, which is the license used by Wikipedia, but the copyright belongs to founder Chris Spackman.
It was formed by Spackman, who had already studied Asian history extensively at university in the United States. While on the Japan Exchange and Teaching Programme he was inspired to create an internet encyclopedia, which he hoped would develop into a broder encyclopedia which would include other information, such as historical documents.
Wikipedia is an online encyclopedia founded by Larry Sanger and Ben Kovitz on January 15 2001 following a conversation between the two friends on January 2 of the same year. It was based on a server in San Diego donated by Bomis Inc. CEO Jimmy Wales, boss of Larry Sanger. The encyclopedia aims to be open and allow anyone to edit it. While the project was quick to expand and had over 20,000 articles within a year, it has also been particularly vulnerable to vandalism, which has been dealt with by a team of dedicated administrators and members.
Everything2, or E2 for short, is an online colllection of writing on a huge range of topics. Content is published in the form of articles called 'nodes' and includes a variety of opinions and facts, ranging from humorous and light-hearted to the more serious.
