Use of electronic journals in a University library: does the Pareto principle work? (Спрос на электронные журналы в университетской библиотеке: работает ли правило Парето?)

Descripción

We consider the empiric Pareto principle (20/80 rule) that describes deviation from uniformity for various processes. The principle is applied to the use of electronic journals in a University library. We analyze 2004 usage statistics for periodicals databases (EBSCO, JSTOR, ProQuest and ScienceDirect) as well as combined data for all 4 resources. We plot demand graphs with respect to different titles and conclude that Pareto principle holds true for the use of online periodicals.
