Abstract
The informetric laws are a set of statistical regularities relating to publications, citations, journals, authors and so forth. First, we consider one-dimensional informetric studies, paying special attention to the growth and obsolescence of literature, and the relations between them. Then we study two-dimensional informetrics: the relation between two “objects” e.g., authors and articles. Such relations, referred to as an Information Production Processes, exhibit certain regularities, which are described by Lotka’s Law, Zipf’s Law, as well as the laws of Bradford and Leimkuhler. It is shown how the h-index and the cumulative first-citation distribution can be described and studied in a Lotkaian framework. The final parts of the chapter describe the measurement of inequality or concentration, as well as the measurement of diversity.
