References and footnotes

Waldo Tobler's (November 16, 1930 – February 20, 2018) publications span between 1957 and 2017, with his most productive year being 1973.[1] Despite retirement in 1994, he continued to be involved with research for the remainder of his life.[2][3] Most of his publications consist of peer-reviewed journals, without single-issue textbooks or monographs, and the quantity of publications is noted as being unremarkable compared to modern geographers.[4] Many of his works are foundational to modern geography and cartography, and still frequently cited in modern publications, including the first paper on using computers in cartography, the establishment of analytical cartography, and coining Tobler's first and second laws of geography.[3][5][6][7] His work covered a wide range of topics, with many of his papers considered to be "cartographic classics", that serve as required reading for both graduate and undergraduate students.[4][3]

The Library of Congress maintains some of Tobler's early work in "The Waldo Tobler Collection," and the UC Santa Barbra Library maintains a collection of his material donated by his widow in "The Waldo Tobler Academic Archives."[8][9] During his life, there were several book chapters dedicated to discussing him, and an entry in the twentieth-century volume of the History of Cartography.[6][2][10] Many of his publications were included in "select publications"[6] or "key readings"[2] section in these chapters. After his death, several articles in his honor discussed his publications, including a review of all his publications in the journal "Geographic Analysis".[3][4][1][11]
