Lotka's Law and Map Librarianship

Lotka's Law states that given the number of authors who have written one article, the number writing multiple articles can be predicted. Though Lotka's Law was based on a study of the chemistry and physics literature, interest has recently developed as to its possible application to the humanities. A test of this general law for the field of map librarianship is discussed, illustrating that Lotka's Law is valid for this discipline.
