History
The principle was studied by linguist George Kingsley Zipf who wrote Human Behaviour and the Principle of Least Effort: An Introduction to Human Ecology, first published in 1949. He theorised that the distribution of word use was due to tendency to communicate efficiently with least effort and this theory is known as Zipf's Law.
Within the context of information seeking, the principle of least effort was studied by Herbert Poole who wrote Theories of the Middle Range in 1985. Librarian Thomas Mann lists the principle of least effort as one of several principles guiding information seeking behavior in his 1987 book, A Guide to Library Research Methods.
Likewise, one of the most common measures of information seeking behavior, library circulation statistics, also follows the 80-20 rule. This suggests that information seeking behavior is a manifestation not of a normal distribution curve, but a power law curve.

Famous quotes containing the word history:
“The history of the genesis or the old mythology repeats itself in the experience of every child. He too is a demon or god thrown into a particular chaos, where he strives ever to lead things from disorder into order.”
—Ralph Waldo Emerson (1803–1882)
“America is the only nation in history which, miraculously, has gone directly from barbarism to degeneration without the usual interval of civilization.”
—Attributed to Georges Clemenceau (1841–1929)
“When the landscape buckles and jerks around, when a dust column of debris rises from the collapse of a block of buildings on bodies that could have been your own, when the staves of history fall awry and the barrel of time bursts apart, some turn to prayer, some to poetry: words in the memory, a stained book carried close to the body, the notebook scribbled by hand—a center of gravity.”
—Adrienne Rich (b. 1929)
