[1] In this paper Tobler created a model of the population growth in Detroit, and was discussing variables included within the model, and Tobler was probably not extremely serious when he originally invoked the first law and instead was explaining limitations brought about by computers of the 1970s.

[5] In this publication, Tobler discussed his less well known second law, which complements the first: "The phenomenon external to an area of interest affects what goes on inside.
[5] An anonymous reviewer pointed out that Tobler's first law is remarkably close to a phrase in a book by R.A. Fisher in 1935.
