For anyone interested in index card systems, the idiosyncratic method of Niklas Luhmann [0] is a fascinating example. Many additional interesting opinions on notetaking and modern database translations of classic note taking ideas maybe found on the website of the translator, Manfred Kuehn [1].

Another interesting and radically less complex example that I have personally found useful is the Pile of Index Cards system. [2]
