History of Mindat.org

Mindat was started in 1993 as a personal database project by Jolyon Ralph. He then developed further versions as a Microsoft Windows application before launching a community-editable database web site in late 2000. [1]. Mindat.org now uses the mediawiki software for its online manual. [2]
