The Knot Atlas is a website, an encyclopedia rather than atlas, dedicated to knot theory. It and its predecessor were created by mathematician Dror Bar-Natan, who maintains the current site with Scott Morrison. According to Schiller, the site contains, "beautiful illustrations and detailed information about knots," as does KnotPlot.com.^[1] According to the site itself, it is a knot atlas (collection of maps), theory database, knowledge base, and "a home for some computer programs".^[2]
