Marxists Internet Archive (also known as MIA or Marxists.org) is a non-profit online encyclopedia that hosts a multilingual library (created in 1990) of the works of communist, anarchist, and socialist writers, such as Karl Marx, Friedrich Engels, Vladimir Lenin, Leon Trotsky, Joseph Stalin, Mao Zedong, Rosa Luxemburg, Mikhail Bakunin, Peter Kropotkin and Pierre-Joseph Proudhon, as well as that of writers of related ideologies, and even unrelated ones (for instance, Sun Tzu). The collection is maintained by volunteers, and is based on a collection of documents that were distributed by email and newsgroups, later collected into a single gopher site in 1993. It contains over 180,000 documents from over 850 authors in 80 languages. All material in the archive is provided free of charge to users, though not necessarily free of copyright. The archive was created in 1990 by a person — known only by their Internet tag, Zodiac — who started archiving Marxist texts by transcribing the works of Marx and Engels into E-text, starting with the Communist Manifesto. In 1993 the accumulated text was posted on a gopher site at csf.colorado.edu. Volunteers joined and helped spread and mirror the main archive. However, the main site and its mirrors were hosted on academic servers and by the end of 1995 almost all had been shut down. By 1996 the website, Marx.org, was hosted by a commercial ISP. This was followed by an increased activity from the volunteers. In the following years, however, a conflict developed between the volunteers working on the website and Zodiac, who retained control of the project and domain name. As the scope of the archive expanded, Zodiac feared that the opening toward diverse currents of Marxism was a "slippery slope" toward sectarianism. The volunteers who had been undertaking the work of transcribing texts resented having little influence over the way in which the archive was organized and run. In early 1998 Zodiac decided that Marx.org would return to its roots and that all writers other than Marx and Engels would be removed.
