Bensman, Stephen J. – Journal of the American Society for Information Science, 2000
This speculative historiographic essay attempts to fix the present position of library and information science within the context of the probabilistic revolution that has been encompassing all of science. Comprises a guide to statistical research in library and information science, discussing skewed distributions, biostatistics, stochastic models,…

Ivancheva, Ludmila E. – Journal of the American Society for Information Science and Technology, 2001
Discusses the concept of the hyperbolic or skew distribution as a universal statistical law in information science and socioeconomic studies. Topics include Zipf's law; Stankov's universal law; non-Gaussian distributions; and why most bibliometric and scientometric laws reveal characters of non-Gaussian distribution. (Author/LRW)

Brookes, Bertram C. – Information Processing and Management, 1984
Four empirical laws of bibliometrics--anomalous number, Lotka's, Zipf's, and Bradford's--together with Laplace's "law of succession" and de Solla Price's cumulative advantage distribution are shown to be almost identical. A simple model shows that the frequency forms conform with inverse square law over appropriate interval. (Fifteen…

Egghe, Leo – Journal of the American Society for Information Science and Technology, 2003
Explains Type/Token-Taken informetrics as a new part of informetrics that studies the use of items rather than the items themselves. Highlights include the frequency distribution of Type/Token-Taken informetrics; the Lotka frequency law; linguistics; a comparison of Type/Token with Type/Token-Taken informetrics; and proofs of theorems.

Bookstein, A. – Journal of the American Society for Information Science, 1997
Examines various kinds of uncertainty in information science. The notion of ambiguity is defined and contrasted with the more familiar notions of randomness and vagueness. Functional forms resistant to ambiguity are defined, and it is shown how to incorporate a random component, that is itself also resistant to ambiguity, into a resilient, but…

Breitenstein, Mikel – Proceedings of the ASIS Annual Meeting, 2000
Presents abstracts of papers for a planned session dealing with the historiography and history of information science. Highlights include probability distributions underlying the use of library materials, particularly scientific journals; the temporal and historical orientation of the rhetoric of information science; and concepts of information…
