Title: On the 80/20 - rule
Authors: EGGHE, Leo
Issue Date: 1986
Publisher: ELSEVIER SCIENCE BV
Citation: SCIENTOMETRICS, 10 (1-2), p. 55-68
Abstract: In a recent paper1 Burrell shows that libraries with lower average borrowings tend to require a larger proportion of their collections to account for 80% of the borrowings, than those with higher average borrowings. In that study, the underlying frequency distribution was a negative binomial. We are dealing with a case when the underlying distribution is of Lotka type. It is also shown that the “80/20-effect” is much stronger in this case.
